Grand Rock Exhaust Stacks: Chrome Truck Exhaust Stacks

[deadmanrip1971]

@ parsleydiesel. Thanks

[deadmanrip1971]

@ parsleydiesal. When I install the stacks should I keep the flomaster muffler on or run straight pipe?

[ParleysDiesel]

@deadmanrip1971 - Your choice. Whichever way fits (with or without the muffler) is how can install the Grand Rock exhaust.

[deadmanrip1971]

@ parsleydiesal. I have a 1984 f250 300 straight 6 gasser pickup with a 3 inch exhaust with a flomaster cat And was woundering if I put a 5inch miter cut stack kit would the backpressure Be ok? Please help

[ParleysDiesel]

@deadmanrip1971 - That should be fine.

[perry244]

could you do this to a 1977 c10 stepside truck?

[TRIALBIKER123456789]

would this cost if i didnt do it myself?

[TRIALBIKER123456789]

im just curious, how much would this be to get it done pro?

[1USMCforlife]

hey do you guys make stack exhaust for gas trucks also? i have a silverado 1500 ls and i wantto put stacks on it, but i cant find them anywhere. plz help me

[ParleysDiesel]

@1USMCforlife - Hey Devil Dog, these stacks will work just fine on your Silverado. Just stick with 4" or 5" tips so you can maintain sufficient backpressure.

[deadmanrip1971]

i have a 1984 ford f250 truck gasser with 300 straight 6 with a 3 inch flowmaster exhaust and i wanna know if its possible to put a 5 in srack kit on it?

[nmtbaseball31]

how do you get the smoke to come out? do you need to do anything special for that to happen?

[Jnoland94]

@nmtbaseball31 This is a diesel truck. Any diesel truck will have smoke come out of the exhaust

[petraitis025]

@parleysdiesel ,what year is this truck and what is it?

[ParleysDiesel]

@petraitis025 - 2001 Dodge Ram 24V

[HeadBreaker26]

What is the difference between the Aussie and Bull Hauler tip styles?, i cant find a picture of the Bull Hauler. Thanks

[ParleysDiesel]

@HeadBreaker26 - They are very similar. The Aussie cut has a sharp, almost 45% bend where the tip flares. The bend in the bull hauler's is softer, leaving more of a curve. There's a picture of all the tips on the product page on our website. You can get to the product page by clicking on the link above.

[bowhunterJohn635]

my 87 6.2 diesel has duals from the manifolds how would i get a kit like this to work?

[megdod209]

so do you have to have a 4" exhaust from the turbo back? i want to install a single stack setup but i have the 3.5" stock exhaust.

[ParleysDiesel]

@megdod209 - If you have a 3.5" exhaust just be sure to add the 3.5" to 4.0" reducer when you order your stack kit.

[1411funnystuff]

Is their ever problems with water getting into the system and rusting it out

[foxtrot1551]

I had a question about back pressure. I have a 7.3 IDI, non turbo. The current exhaust 3 inch all the way back. Could i just get a reducer from the 6 inch to a 3 inch, and still be alright?

[ParleysDiesel]

@foxtrot1551 - The plumbing on this stack kit is 4" under the bed of the truck, so you would order the 3" to 4" reducer, along with the 6" exhaust stack tips you prefer.

[archeryrox7]

Do you guys have a kit that would fit a 1985 GMC with a 6.5 liter diesel?

[ParleysDiesel]

@archeryrox7 - These kits are universal. They will fit in your truck, you'll just need to order an appropriate reducer to fit your exhaust diameter to the 4" flex pipe diameter of these stack kits.

[MrKomets20]

Ive wondered, i have a 95 Ram 2500 and the toolbox i have in the bed i need for work, so what im asking is, does the t-pipe have to be in the bed of the truck? or can it be underneath with 2 holes for the stacks?

thanks

[derkaderkastan420]

@MrKomets20 bad idea there... did you ever think of just sliding the toolbox back 6 inches?

[kniffriff]

can you guys make one to fit a 2005 ford f150 4.6L v8?

[ParleysDiesel]

@kniffriff - these kits will fit your F-150, but you have to go with 4" diameter stack tips so you can maintain sufficient exhaust back-pressure for your gas truck.

[VidKidd22]

talk about powerful looks good btw.

[gallodehuetamo]

what happens if it rains on the stacks.

[GinoJerry86]

the mufflers dont make a difference

[66sucks]

is there kits to just go from the headers to the stack? i plan on taking the bed off my truck and running stacks. basically it'll look like a big rig but a 69 C10 long bed. gonna put some fat drag tires on the back and all that good stuff. cant decide between a big block or a small block. for money purpose i might go with the small block. but id like to go straight from each header to the stack with no Y pipe involved

[Venom746]

do you sell the internal muffler separately or no?

[ParleysDiesel]

@Venom746 - Yes, just call us at 801-938-4891. We stock the internal mufflers and sell them separately.

[bobbygreenthumb]

@ParleysDiesel I have a 2011 dodge 3500 I want stacks but everyone tells me to wait cuz it'll void my warrenty any advise? Is there stacks that won't void warrenty?

[ParleysDiesel]

@bobbygreenthumb - Universal exhaust stack kits such as those made by Grand Rock will not fit on a DPF-equipped diesel truck. To install the exhaust stack system you would have to make major modifications to the emissions control equipment, automatically voiding your warranty.

[randytune88]

@bobbygreenthumb no because you have to cut a hole n the bed and remove the dpf.

[DuallyDieselFord]

How does rain get out?

[Picklepete37]

they are sick dude i gonna have 1 like that!

[bluejay148]

sweet

[dumapies]

i would hesitate to attempt this myself

[drizzetsrevenge]

Lookin good guys!

[95dodgediesel]

i like how he says optional mufflers!

[Dustpan04347]

@95dodgediesel they shouldnt even be an option. honestly, who gets stacks and puts a muffler on em??

[CSXtrackworker]

@Dustpan04347 Truthfully dustin the internal muffler's really don't do anything except act as a soot catch.

[bireckford]

can u mount the y below the box ?

[ParleysDiesel]

@bireckford - No, not really. It isn't designed for that.

[durkization]

@ParleysDiesel how long does this take to do???

[ParleysDiesel]

@durkization - It really depends on your equipment and level of confidence. The installation isn't difficult. Anywhere from 2-4 hours is average install time, but some guys do it in an hour and a half, others just enjoy the process and take an entire Saturday installing their kit. After all, anticipation is half the fun!

[Dustpan04347]

@bireckford you would have to get around the drive shaft somehow either under or over it. and then you'd have two holes in your bed.

[erk409]

air drill..

[Fish0jens]

Do you lose power if you remove the catalyst?

[bomberhockey22]

is there alot of drone in the cab with mitre cut stacks?

[Denniswillwreckthee]

How do you get all that smoke to come out of the exhausts?

[Denniswillwreckthee]

How do you get all that smoke to come out of the exhausts?

[shaneross11]

i put a set of these on ym 06 dodge and thought i would comment what i found. when cutting the hole i did have to notch the cross member, but then one side of the saddle bolt also was placed right into the center of the cross member making it impossible to put a nut on it.there is a square hole on each end of the cross member where you can fit the right size socket in. i would suggest drilling a hole in each one then lining up the second hole with the bracket so that you can get a nut oneachside

[clipdan]

pretty sweet, but I would install rain caps, or bend the tips back.

[jonjeny]

as DolittleMccoy said.. what happends when it rains??

[DolittleMccoy]

awesome!!! I've always liked straight stacks better then the ones with a bend... Just wondering if alot of rain and water gets in the straight stacks when parked, Or is that no big deal if so?

[johndeere10100]

sounds nice i have a 2002 gmc diesel i wanna install dual stacks

[fordmustang500kr]

i think it sounds nicer with mufilers in

[rbarryfamily]

How much is the whole system? I have a 2009 f-250 with the v10. They sound awesome with the stacks also. You have to love the diesels though. Please reply.

[ParleysDiesel]

Depends on which size stacks and what tip style you get. Somewhere from $500-$900 on average. Go to our website and price out a set. Just remember with a gas truck you need to maintain sufficient back pressure, so don't go over 5" stacks.

[rbarryfamily]

Thanks man!

[pewterfun]

shoulda left the mufflers out!!!

[Citadel2010]

if i saw a tech driving my truck like that i would be pissed!!

[ParleysDiesel]

What makes you think it's not his truck?

[Citadel2010]

@ParleysDiesel just talking about in general! thats not my truck so i could care less!

[CSXtrackworker]

It's a truck, not a barbi ferrari.. That isn't going to hurt it.

[SMOKINU497]

@Citadel2010 Thats Kyles truck from G and R diesel... The truck is owned by the guy who is burning out in it... "the tech"

[dakotaerin6]

what if you run it straight

[Ainaloa]

Deep sound, just awesome!! I hope to save up for a Diesel lol Great Vid!!!!

[eshapiro92]

how much would this cost to install?

[porsche911turbogt3]

YOU DONT TAKE OF THE DPF

[dieselpower4ever]

What diameter are those stacks their?

[ParleysDiesel]

Those are 5" Mitre Cut.

[davidblainesbetter]

i like that truck how many inches would you say is that lift and tires?

[ParleysDiesel]

The mufflers make a little bit of a difference.I don't know what it equates out to in decibels.

[EnlargedProstrate]

I bought the single Grand Rock stack. How much of a sound difference will the internal muffler make?

[ParleysDiesel]

The mufflers will make a big difference in sound quality. As far as hp/torque 5 to 10 percent increase depending on what you are driving, and if you have installed a intake and or any other mods.

[Proverbs3030]

also how much diffrence in sound does the muffler make? and how much more hp/torque on average do stacks add?

[Proverbs3030]

Im about to put some on my 92 dodge 250 standard cab cummings diesel. I watch your video and it helped alot thank you. but I have a question, would i need to remove my stock muffler on it to put the stacks on or do I kep the stock muffler on? Thanks guys your amazing!

[Proverbs3030]

Im about to put some on my 92 dodge 250 standard cab cummings diesel. I watch your video and it helped alot thank you. but I have a question, would i need to remove my stock muffler on it to put the stacks on or do I kep the stock muffler on? Thanks guys your amazing!

[ParleysDiesel]

It depend on the location of your stock muffler. Most likely you will have to remove it. Just figure on cutting and tossing everything in the current exhaust system from about one to two feet forward of where the truck bed starts.

[Proverbs3030]

Awesome. Man you guys are so helpful. Thanks so much. You guys are amazing! Keep doing what your doing, all us people out here appreciate what you do. :)

[ParleysDiesel]

Usually between 600 and 800 dollars depending on size and style that you buy.

[Leprkan83]

whats does it roughly cost for this setup?

[CSXtrackworker]

Leprkan, it is well worth the money. I just purchased a dual stack set& it was well worth the money. Even though my silverado isn't a diesel, it sounds great, and seems like it runs better& quicker!! Well worth the money dude!

[89silverbullet]

Its a 24 valve. It's a quad cab.

[ParleysDiesel]

Yes, you can go back and easily add mufflers later if you feel the need.

[Lars4465]

Is it possible to install the kit without mufflers and later put them in if necessary? I'm assuming you would be able to unclamp the stack tube and slide the muffler in but not sure

[123sombitch]

y wud u put stacks on a gas truck wont even smoke

[ParleysDiesel]

Because even if someone doesn't have a diesel you know they wish they did, and because stacks just look sweet. Simple as that.

[CSXtrackworker]

because no matter what, they will look good, and done right& properly installed with this kit they will sound good too... I would like a duramax, but I do not haul heavy enough loads to justify spending almost 50,000... My truck is rated for 9,600 lbs towing, and the most I tow at any given time is 6-7,000 lbs. I have seen half ass jobs that look and sound like shit on gas trucks. With this universal kit, it solves this problem. I'm not worried about smokeing, I just want it to look& sound good.

[bk32591]

what motor is in that dodge?

[CSXtrackworker]

My guess would be the 12 valvr cummins.

[GreyGhostZ71]

thiis is probably a stupid question, but with those kind of stacks, what happends when it rains? like wat happends with all the water that gets into them?

[djcheck32]

there are some stacks that are bended at the end or there is a tap the every time you hit the gas opens

[bigmike97dak]

Im about to order this kit for my 1997 dodge dakota cc 5.2 v8. Im gunna be the first guy around my town with stacks. But was wondering what is the difference between your exhaust stack and my local custom exhaust stacks other than price theres is 200 yours is 500 last I checked And would you cut me a discount if I flew a grand rock stacks flag from my bed mounted flag pole and rocked some window decals??? Like a sponsered rig? Just wondering get back to me please!

[dirtboy100]

trush tubes?

[fordbeast350]

cuz i want to have a 4" exhaust. so i need the downpipe and the pipe to reach the back of the cab, where the bed starts...pretty much where the elbow starts

[fordbeast350]

so do you guys have a 4" down pipe and 4" tubing up to wherethe stack kit starts??

[Flattrack450r]

i didnt notice much of a difference with the internal mufflers

[drunksingsheep]

vermont? the scenery looks fam.

where are you at man?

I dig Glass Packs!

[fordbeast350]

do you guys have just the 4 inch down pipe so i can have all the piping as 4 inch. cuz i want the stacks but i dont want the reducer. i want the whole thing to be 4 inch down there. just wondering if you guys have that. and about how much$?

[ParleysDiesel]

The stack kit comes in 4" by default. The only reason you would purchase the reducer is if you had a stock exhaust system of 3" or 3.5".

[ParleysDiesel]

No, you would have to buy just the tips you wanted and have custom fabrication done for the rest of the exhaust work. All our kits are currently inside the bed only.

[aguilar1508]

do yall have stacks that can be installed outside the bed?

[mleenoy]

where are your safety glasses???

[CricketPrime]

can you pass emissions tests on a regular gas truck? and how loud are these when you are in the cab? thanks

[ParleysDiesel]

They are loud. You'll want to check with your local emissions tester to be sure.

[cummins143]

what size lift and tires do u have?

[MoparHP]

I have a regular cab/longbed configuration. My Cummins Ram also has one of those pesky Diesel Particulate Filters. Is it possible to run stacks, while still keeping the D.P.F. attached, for the sake of keeping the truck street legal???

[ParleysDiesel]

it is possible, you might have to add a piece of pipe to S back to hook up to the kit, but they are definately doable.

[07dodgecummins07]

im running into the same problem, i ordered a kit from MBRP and im just going to kinda nigger-rig my own, cuz mine has the dpf to and they dont make a kit for a quad cab-shortbed but i odered it and im waiting for the man in the Brown truck to bring it to me, i'll post a vid wen i get it done!

[southerndiesels]

no welding required?

[Sk0alRebel]

Is it possible to put a stack on a 150 non- diesel

[ParleysDiesel]

They are universal kits, you just have to use a reducer to get the exhaust to fit where you hook the kit up to your stock exhaust.

[CSXtrackworker]

I just bought the straight cut 6 inch stacks with internal mufflers for my 08 silverado with the Gas 5,3 ltre. I would like to know if there is a sound difference between the straight cut& the bull hauler stacks?

[maxpower14843]

i love how it sounds without the muffler but i live in NY and it is required by lay and all of the filters

[DaRkAnGelOwNeR]

damn i hate them lays.

[popo953]

southerndiesels couldn't you just put that 90 degree pipe and put it on its side and than purchase another 90 degree pipe up so it would be on its side would that work

[southerndiesels]

Im not quite sure what you are trying to say, but if you google image search International CXT you will know what I am talking about

[Jorge50505]

does that have the cat?

[fballbud]

cool vid

[brewskisdodge]

so for the whole you cut in the bed is it a 4" hole or a 5" hole.....nice vid!

[ParleysDiesel]

It was a 6 inch hole, because the bottom of the pipes has a Y that has to sit down in the hole, so the hole has to be a bit bigger than the pipes.

[southerndiesels]

I want to get stacks on my truck, but bed space is crucial to me and im also thinking about putting a dump hoist kit under the stock bed for dumping. Now obviously this interferes with drilling and putting stacks through the bed. So is there any way I can get my stacks to run out of the side of the truck? Just like they do on the International CXT. And if so do you still have to move the cross member? And who can sell me a kit like that?

[ParleysDiesel]

It sounds like what you're needing will have to be custom. you might give grandrock a call and ask if they have the different parts to do that.

[southerndiesels]

alright thanks

[FordDZLMan9191]

I couldnt really tell a difference with the mufflers and without. it sounded pretty much the same.

[ParleysDiesel]

you can tell a little difference in person, but it's not anything dramatic.

[FordDZLMan9191]

maybe its more of a cover you butt kinda thing "oh yeah officer, I have mufflers..." lol

[fckinchit]

why not make a true dual instead of using the "y" pipe?????

[Dempsey187]

it an inline dodge so it only has one header

[fordbeast350]

are these legal in california?

[Motocross1110]

Im pretty sure its cool, last I heard you can go straight pipe because the turbo is considered an emmision control device. I'm doing it and I live in the folsom area where the pigs will ticket you for tinted windows and not coming to a 100% complete stop.

[goshenx132]

question, can you use your front bed tie down hooks or are they behind the dual stacks?

[progamerIII]

what a turd

[walkingfreak]

haha i like it better without the internal mufflers i am so going to leave out the internal muffler when i finally get my diesel truck

[CricketPrime]

aRE YOU STILL ABLE TO PASS EMISSIONS TESTS?

[finalfantasyXyuna]

why wouldn't you? its just rerouting the tail pipe to make it a stack.

[motorrulo]

sino fuera por ese humo negro aun podria quedar mas o menos bien

[Gazooo29]

I have two questions

1,How Much Louder Is It in the Cab with the Stacks,

2,How Will Snow,Ice etc Effect your truck with these stacks.

Is there a Drain Valve at all

[ParleysDiesel]

1) Stacks are loud.

2) the only stacks you really have to worry about moisture with are the straight cut, which is the flat top stacks. when you turn on your truck it vaporizes any moisture in the pipes.

3)You can't install your own drain valve if you want, it doesn't come with one. And it's not really neccesary.

[riverviewpowerhouse]

do they work on gas trucks

[ParleysDiesel]

yes they do, you just need a reducer to make them fit to your stock exhaust

[fiapoko1]

could i put on a set up like that for my dodge1500...???

"H"

[ParleysDiesel]

They are universal kits. They work as long as you have a normal truck bed.

[fmfracer5590]

k so im thinkin about gettin the mitre cut but the only thing im afraid of is water gettin inside the pipes, if i dont cover them what will happen?

[ParleysDiesel]

You'd have a little smoke when you first start the truck, and it would just be the water being vaporised is all.

[CumminsTurboDiesel12]

Wouldn't it seize up the motor if water got into the pipe?

[ParleysDiesel]

the pipe under the truck is lower than the pipe that comes off the engine, there's no way for water to get to the engine.

[CumminsTurboDiesel12]

O ok Thanks. Just was wondering lol.

[tadj123]

does that truck have a chip in it? cause i know that will help blow alot more smoke

[fmfracer5590]

are those 5 inch mitre cut or are they 6 inch mitre cut

[ParleysDiesel]

they are 5 inch

[brehmerboy]

i wouldnt of minded the exhaust that was on there first

[psiCUMMINSboost]

i just bought a set for my cummins will i smoke like that with just the new stack? or do i neeed to do more work

[s172mch]

depends

its a 12v right?

u might have to get a chip/programmer for more smoke

[psiCUMMINSboost]

i have a 97 cummins and just ordered those stacks will it have black smoke? or will i have to do more.

[Davidflapjacks]

dude, could you do my truck in 2 years?

i want 7" curved top stacks and big tires!

[MZackM]

Is there a loud drone or noise when you have stacks on your truck? Like is the noise loud inside the cab of the truck when driving?

[quader94]

insince the left stack is farther away from the hole then the right stack...i might sound dumb but does that make them smoke unevenly?

[tjcram05]

a lot of times they do smoke a little unevenly, but usually it's not really all that noticable

[grizzlyman239]

so it is louder with out the internal muffler?

[ParleysDiesel]

yes, without the mufflers it is louder. There honestly isn't a huge sound difference. In the video there is a sound clip with and without the mufflers.

[jeighner]

what lift and tires were on that rig, and 5" stacks?

[tythesnoman]

awesome awesome video!!!

[blacksabbath112205]

very nice video.. when you installed the stack permently were they with or without mufflers?

[ParleysDiesel]

Without mufflers, we like as much sound as possible.

[W6e6s6W]

Spray-in liner in there?

Looked tough to cut through lol.

Good step by step walkthrough though.

[DieselBlooded19]

acutal it sounds almost the same with them with or without the internal mufflers which is good for cause if i recal in our state its manditory too have mufflers

[ParleysDiesel]

In person you can tell the difference a little better, we had the mic a little too close to the truck for that sound clip.

[DieselBlooded19]

ohh ok by the way i dont kno if its me but i didnt really see too much about the internal mufflers on ur web page about the kit do they come with the kit or do i have too buy them seprate and if i have too buy them seprate do u guys offer them?

[ParleysDiesel]

It's on the right side at the bottom of the options section. The web guys just added it.

[DieselBlooded19]

thank you sir

[CSXtrackworker]

I have a question. I just orderd 6 inch dual straight cut's stacks with internal muffler's for my 1500 silverado with the 5.3 ltre v-8. I would like to do bullhauler's, and my question is, will bull haulers sound different than that straight cut's?

[ParleysDiesel]

They won't change the sound, but they will direct some of the exhaust note away from the cab so your ride might be a little quieter inside the truck, but outside it will sound pretty much the same.

[CSXtrackworker]

Ok thankyou for the info!!! I appreciate it!

[cumminsdiesel1234567]

Boy that thing sings w/o them internal mufflers.
