1990 S-10 4.3 V6 with flowmaster 40 and highflow cat

[jharrelson18]

has your gas mileage decreased at all? im thinking of this setup on my 03 sonoma.

[thomasmcmullen06]

I cut the cat off the s10 i had and put a super 44 on it, it sounded just like a v8, I plan on doing the same with the s10 blazer 4x4 i picked up

[superchevy881]

I just had my dual cherry bomb glass packs taken off and the FLOWMASTER SUPER 40 2 1/2" pipe into 3" tips God that shits awesome love your setup mines the 1993

[Johnathinmitchell1]

it sounds a little too busty but it sounds good it has that bad ass v6 rummble!. me myself i think v6 is the way to go yes v8 has more hp n tq but i cant get enuf of the way my v6 runs n sounds i dont have any vids of it on here but ill make 1 or 2 of a get down 25-60 n rev up its a 94 gmc sierra 4.3 262 v6 vortec flowmasters dumped!. ttyl

[James89RL]

sounds real good for the six man awesome! you did it right with the high flow cat on top if it all! the computer does not throw a code from the set up does it?

[jmc6000]

@James89RL No code thrown since in 1990 there was not an O2 sensor after the cat.

[wsimpson86]

@James89RL It's OBD1 only has an oxygen sensor to adjust fuel trims.

[RIDEinAKallDAY]

nice sound awsome check out my 93 s10 on my channel

[iamscum21]

sounds good i gotta 93 its got true duels and two glass packs the packs are welded together and the pipes are welded at the tips and yea its for looks but i looks good and sounds good to

[guardian22553]

that truck is perfect i have the same one was it really a 60 autozone muffler lol thats crazy if it was now i want one lol

[escalade26esv]

is it true duel? and how much was it?

[themadhacker2]

sounds good, but mine has the cat removed :D

[MegaGizmotron]

Beautiful just Beautiful

[124maddog1]

What kind of cat do you have?

[jmc6000]

@124maddog1 60 dollar autozone special!

[MrKharper123]

Sounds Good Bro! I am going to the muffler shop today to take off a Thrush Welded and put on a Flowmaster 42441. I am considering him put on dual pipes out the back. Will that make a difference??

[jmc6000]

@MrKharper123 No difference, dual pipes are just for looks.

[automotiveDIY]

@jmc6000 only for looks unless its a true dual setup

[LGXYFTW]

@jmc6000 Btw man thx for posting this vid this vid made my decision on what exhaust to get on my GMC Sonoma only thing i need to get now is some nice tips

[GMCman82]

@MrKharper123 actually,dual exhaust can benefit you.done properly you will gain a little extra hp and torque but it should be true dual exhaust (2 individual pipes) use the proper diameter pipe for your engine's output and use a flowmaster or such.i did a cat and muffler delete ran stock pipe to longe tube large diameter cherry bomb glass packs. stretched the outlet to 3in and put long tube tips. didnt care if i lost power,sounded badass and my 3:73 gears made up for it. actually gained a little

[MoFo5043]

Nice!

[HotshotMC2]

I have a 91 s10 and I wanna know what kind of high flow cat did you use becasue I wanna use one with a cherry bomb extreme muffler.

[jmc6000]

@HotshotMC2 Autozone 60 dollar special!

[LGXYFTW]

@HotshotMC2 Tbh I got the exact same thing just today minus the tips and used the orginal cat that was on mine and sounds the exact same,I asked the guy about high flow cats and he said its a gimmick. He said if you went into any place and asked for a high flow cat they would just hand you a magnaflow or some top brand name cat. Im up in Canada but just thought id give you my 2 cents i will have the vid up of my exhaust soon to show you that i dont think it matters if its high flow or not.

[HotshotMC2]

@LGXYFTW Well thanks, you just saved me $65 on a magnaflow high flow cat that I don't need.

[burnbabey12]

@HotshotMC2 with a 91 s10 you don't have tp have to have a catylatic converter as long as there isn't a O2 sensor after it. all cars 97 and newer has to have a catylatic converter. 96 and older dont have to have one by law but it might depend on witch state you live in too.

[HotshotMC2]

@burnbabey12 I know it has the O2 sensor b4 the cat and i can take it off but it will kill my gas mileage cuz there will be no back pressure. I'll probally still go ahead and get a high flow cat anyway.

I'll get this ebay.com/ebaymotors/ws/eBayISA­PI.dllViewItem&item=1904903791­12&viewitem=&sspagename=STRK%3­AMEWAX%3AIT

[burnbabey12]

@HotshotMC2 actually back pressure is what kills your gas mileage... back pressure is good on a two stroke but not a four you want to minimize as much as possible to get more power and more miles to the gallon.

[HotshotMC2]

@burnbabey12 Actually not having enough back pressure can kill the mileage.A cars engine is set to work smoothly with a certain amount. Too much or to little can effect the performacne and gas mileage. It needs to have some restriction to work properly. That is if you wanting to use your truck as a daily driver and still wanna get good mileage like me. Otherwise take off the cats, the muffler and just run straight pipe. 8mpg lol but loud and sounds cool.

[burnbabey12]

@HotshotMC2 Im sorry but that is a myth i have built and raced both circle track and drag cars and trucks back pressure restricts the motor by wasting the engines energy trying to push the exhaust gases thru a restricted system. Back in the day when things were carburetor the back pressure would shove some of the fuel air mix back into the carb giving it a second shot of fuel but reducing the back pressure didn't alow the engine to do this now the computer in cars fixes this today...

[burnbabey12]

@HotshotMC2 Oh and opening up the exhaust system allows the engine to run cooler puts less pressure on the heads and allows more room in the cylinder for more fuel and air mixture......

[GMCman82]

@HotshotMC2 as long as you keep the proper size pipe for your engines out put and you have enough pipe length you dont have to worry about back pressure. if uget headers with a slightly larger diameter collector , it should still be ok, but you can always put a reducer on it. im getting ready to do a cat delete on my 5.7 sierra, im leaving the stock size pipe on it and keeping the same length and i already have flowmaster super 40 delta flows on it. it is true dual exhaust which also helps

[Pegs2001]

That brought back memories. I used to have a 91 sonoma with the same black paint and 4.3L engine when I was in high school.

[mfarmakas17]

that is honestly the best sounding v6 i have ever heard. is this carbed?

[jmc6000]

@mfarmakas17 Close, but it is TBI (throttle body injection)

[mfarmakas17]

@jmc6000 i hate tbi so much haha

did u just swap the muffler and cats or did u do a fully custom exhaust?

[215rant]

is it a Y pipe?

[jmc6000]

@215rant Yes, it is factory.

[215rant]

@jmc6000 sorry but does that mean it cameout like that?

[jmc6000]

@215rant Yes the y-pipe on the truck came from the factory with that y pipe.

[jbm1137]

sweet sounding truck for a v6:)

[beeforonie]

i have a 90s s 10 truck and me and my dad puta 350 in in and i have true duls going back to cheery bombs i have a set of flowmasters and tips i wanna put on it.

[irarawkstarr]

The boxy 1993 and back S10s are the best.

[215rant]

is that a s10 truck or s10 blazer?

[jmc6000]

@215rant S10 truck.

[sjmorris71]

@jmc6000 Great sound!! I have a '98 4.3 Vortec that I want to sound as aggressive. I know it won't have the deep mean growl as a V8. But that is as close as you can get with a V6.

[buffguy0]

@jmc6000 That is the BEST v6 setup ive ever heard plz tell me what all u got on there so i can make mine sound just like that PLZZZZ LOL

[swordsman2070]

@215rant are you kidden look at the tail gate and tell me thats a blazer

[215rant]

@swordsman2070  i got a 89 s10 blazer and it looks the same

[REDT4R1]

@215rant Did you really ask that..lmao The tail gate handle is showing man...lol

[trunk516]

I've got a 91 S-10 with the anemic 2.8..but I cut out the cat and put on a 30 series flow into twin tips and it also sounds like a v-8..hard as that is to believe...

[shotgunwilly101]

it would sound better with CHERRYBOMB EXTREAMES and flowtech headers and a cherrybomb catlatic converter

[shotgunwilly101]

it would sound better with CHERRYBOMB EXTREAMES and flowtech headers

[jcthemack]

nice check mine out !

[jmc6000]

delta flow, but the super 40 is a good one as well.

[HotshotMC2]

What are all the specs on the exhaust you running because I have a 91 and I want the sound you got on yours.

[jmc6000]

@HotshotMC2 Stock Y, highflow cat, single pipe all the way back to one flowmaster 40 and then dual 2.25 out all the way to the back.

[HotshotMC2]

@jmc6000 alright found the flowmaster 40 but theres like 4 different ones. Which one? Classic, Delta flow, Orignal, or the Super 40? And what brand of highflow cat?

[drifter5064]

dual? or no and how much was it......I got a 4.3 s10 blazer and I want it to sound just like this :)

[jmc6000]

@drifter5064 Not true dual, and the system was already on the truck when it was bought!

[313foxbody420]

yeah the smoke is JUST from burning oil. when you start up your motor, it needs time to warm up to operating temperature, because when it is just started, the pistons are cold and therefore have not had time to expand, making the clearence between piston and cylinder wall smaller, and getting a tighter seal. when you rev a cold motor, oil is left in the cylinder and then burned upon the next power stroke. thats why i reccomend warming an engine before a video.

[jmc6000]

@313foxbody420 Acually bud the engine was fully warmed when I recorded the video. The tad bit of blue smoke is from worn valve guides that are very common on old small blocks and the 4.3 as well.

[313foxbody420]

@jmc6000 thanks, bud. enjoy the frame hanging down 6 inches past the body line. chevy stopped making trucks when they switched to IFS, and the frame hanging down. their last real truck was the chev k10. the greatest truck ever made. and because we cant take over a couple of countrys with oil, we gotta pay, and now we cant drive these great classics because they suck fuel like a vacuum cleaner. well, at least we have the small s10's, and rangers to cope with this. see you at the trails, bud.

[Twinkmasta1]

@313foxbody420

"because we cant take over a couple of countrys with oil, we gotta pay, and now we cant drive these great classics because they suck fuel like a vacuum cleaner."

Well spoken (:

[TooManySnakes]

I put a dynomax ultraflow and mandrel bent tail pipe on my buddies 4.3 vortec. Maybe it's the vortec heads but the sound from that is a bit less boaty.

[RichardSoullie]

oh ok i was wonderin on more of a performance note, do u notice more power with the high flow cat sounds good by the way!

[jmc6000]

@RichardSoullie Well it was way better than the stock cat which on this truck was clogged with soot and oil since the orignal 4.3 had a rod knock and wasnot running to well.

[RichardSoullie]

@jmc6000 ya i finally got my exhaust done this summer, i put up some vids, i went and had magnaflow high flow cat put in too

[RichardSoullie]

is it worth it to buy the high flow cat, im in the process of shopping for an exhaust system for my 00' s10

[jmc6000]

@RichardSoullie If you live in a state that does emmsions testing then yes!

[bmxzach]

this is perfect. 

[sidtubenut]

That's the sound that I want from a 2.8L chevy. I wonder?

[TooManySnakes]

@sidtubenut not gonna happen...

[JuliusLeddy]

the Chevy 250 4.1 L6 sounds exactly the same when using a 6x2 headers

[xXxtheROCKSTARxXx]

dude it sounds great.

[chrisholloway12]

cleanest setup yet

[ENJOITHEKILLCAM]

hey there does anyone know if they make aftermarket exhaust systems for a 1991 gmc jimmy i just cant seem to find any thanx. that truck sounds nice btw

[joelin66]

That awesome man ,sound great for me

[91trxryder]

the water and oil comin out yer pipes means u need new haed gaskets ans piston rings lol just thought id help

[jmc6000]

@91trxryder Acually the water is from water vapor that comes out of all exhaust systems perticulally on a 50 degree day with 100% humidity. The oil is from bad valve guide seals.

[91trxryder]

@jmc6000 oh yeah ok. yeah thatd do it. sounds good tho

[gmcsonoma1]

whats the setup for this, is it true duals or y pipe into duals

thanks

[jmc6000]

@gmcsonoma1 Stock Y pipe into the muffler and then out of the muffler as duals.

[75GMCman]

That sounds awsome!!

[weewoodeal]

any one know where i can buy a new 4.3 short block?

[WFO355]

Google it. I have found them by doing that before.

[weewoodeal]

i did google it...that is why i am asking if anyone knows .... duhhhh

[WFO355]

napa sells them as a crate motor for like 2,000$

[weewoodeal]

o ok...ty

[215rant]

Very nice!!

[dandanzoo]

now i must get a flowmaster for my 4.3 1994 blazer i just replaced the exaust with a high flow cherrybomb cat. and some cheap shitty muffler but now gunna cut that fucker right off and get me a 40 series that sounds sick man.

[UprightsRule895]

Heyy man i got an '84 with a 2.8 that I use for goofing around in the woods (so it has no cat) and want to run true duals. What do you think has the best tone?

[stickfishy]

@UprightsRule895 a torch an welder

[metalhead2293]

hey @jmc6000. i have a 93 s10 pickup. I'm fixing to redo the exhaust. I don't know if i should get flow master or glass packs? also are you running single exhaust to dual, or regular dual exhaust? by the way i love the way your truck sounds!

[jmc6000]

Go with a chambered muffler like flowmaster or something simular on the 4.3. Anything eles would sounnd like crap. BTW, the truck was runing a single 2.5 inch pipe into the muffler then dual 2.25 inch pipe out of the muffler.

[rickpat26]

so when you say highflow cats what you mean.

[jmc6000]

A cat converter that allows more exhaust gas to flow through it than the stock one.

[rickpat26]

oh ok bc when i hear highflows it gets me lost then hearing magnaflows cats or something. I was gonna take mine off but their welded together.

[jmc6000]

Most Magnaflow cats are a brand name of a highflow cat.

[Brendon9494]

@jmc6000 how much r those?

[jmc6000]

Get them off of Summit Racing for about 60 to 70 bucks.

[paul42489]

nice truck bro, makes me regret selling my 1990 s10. now i roll in a 2003 zq8 but i still wish i had the old girl. nothing like it. i have a couple of vids of it. check them out sometime.

[454sskilla]

can someone tell me how these 4.3's go. probley pretty good for that small truck

[jmc6000]

You they hold their own, denpending on the model of 4.3. They are different versions of this motor out there.

[scottyBoland]

gms a good 4.3 though my bravada made it through almost 200,000 miles before the first breakdown

[rickpat26]

@454sskilla I have a 2003 s10 Zr5 V6 4.3 Crew Cab and it runs great

[BIGWHITE250XL]

40 series all the way dude. haha like you said for my V10 sounds the best

[kevinmark4]

HAR

[jmc6000]

huh??

[kevinmark4]

haha

[jmc6000]

What is so funny? I bet this truck sounds better than your car, yeah that would be funny!

[kevinmark4]

im not laughing at ur truck. i have a 91 s10 and urs sounds better than mine

[jmc6000]

Ah, thats ok, I don't even have the truck anymore!

[martyrhate]

i can't wait till i get my 95 s-10 4.3 vortec going i like the sound of yours

[jmc6000]

Is your 95 throttle body injected or central port injected? If it is CPI it will sound even better than the my old 90 with TBI. The CPI motors have a higher lift cam in them from the factory! Hence the reason why they were called the 4.3 Vortec HO!!

[ajd157]

MAN!!! your S-10 really makes me wish i still had my sierra. it also had a 4.3. but i had a 50 series on it.

[2011freeze]

Is it hard to get a 2000 4.3 to sound good? ..how will it sound if i leave the stock cat on there?

[mynutsareonyourchin]

dude. out of all the exust vids, ur s10 is the fucking best.

[jmc6000]

Its not hard to get an old 4.3 to sound good!

[mynutsareonyourchin]

i just ordered a flowmaster for my s10, ill put up a vid when i get it on !

[kreigsmann]

whyd you get a high flow cat?

just cut it off and leave it off...

still sounds great

[jmc6000]

In Delaware you do not want to get caught with at least some form of a cat on there.

[kreigsmann]

you cant be cought with a cat?

or without

assuming you meant without

how would they know you dont have one?

i never had a cat on any of my cars in the states i lived in i never had a problem.

just take it off.....

[jmc6000]

Well when you get it inspected there has to be one on there and my dad is too lazy to replace a striaght pipe with a cat every time it comes around for inspection.

[kreigsmann]

well ide be lazy too!

well it depends who you get it inspected by

dont go to jiffy jube or some place that does it professionally

just go to some hole-in-the-wall shop that has a state inspector sitting around adn theyll pass anything.

[tucsondog]

love it.

[jmc6000]

No, but it was bought at Autozone and they had it in stock.

[2011freeze]

was the cat made for the s10?

[jmc6000]

No. Universal 2.5 in/out!! Donot get direct replacment, it will cost to much!

[2011freeze]

Do you know the brand of highflow cat that's on it?

[BassRacerx]

this truck sounds nothing like all of the other s10s with flowmaster 40's i like this one better

[jmc6000]

Highflow cat with the a single regular 40series will get you very close. ;-)

[jreese66]

thanks man..i want to avoid having my s10 sounding like the hondas with big mufflers on them..they sound like mopeds.

[jreese66]

man i love that sound i just brought a 91 chevy s10..can you give me some advice on how to get it like this

[1984chevs10]

that's a mean soundin s10, i like it a whole lot

[elfishgrin]

Meh, I like the lumpier cam noise of the v8's :S less rev more rumble :)

[967527]

so it really is a regular 40 on it n the stock cat on 90 s10 wud i get the same sound if i leav it on

[jmc6000]

Stock cat is too restictive!

[jmc6000]

Acually it will be a tad bit louder and little raspy in the upper rpm range.

[gamefarm83]

And this is the standard 40? I definitely think this is what I want on my s10 blazer

[jmc6000]

Regular 40 on her!

[gamefarm83]

My cat is a gutted stock one. Think i'd get the same sound with just the flowmaster 40?

[BassRacerx]

i really like that back bumper on that s10 what dieamiter piping is all of that?

[jmc6000]

2.5 single from the cat to the muffler then 2.25 dual out of the muffler.

[otter4x4]

Sounds really good, dude. Is that cold weather steam or smoke?! Haha.

[jmc6000]

A little bit of both, haha! It needed valve guide seals, just like a an old 350.

[Kenny42581]

hey dumbass thats a 4.3 not a 2.8!!!

[xX53preble53Xx]

how much this cost u

[jmc6000]

the exhaust was n the truck when it was bought from the prevous owner.

[Absolution923]

Sounds awesome, I'm thinking about the same set up.

[86redbird]

Sounds really good for a v6. Good idea with the hf cat. Without it the V6 engine usually gets a bad sound.

[Booger8993]

very impressive. i gotta 93 s10 w/ a Thrush Turbo II dump and no cat...

love the way ur's sounds tho

[Keitherr18]

that year 4.3 didnt come with roller rockers. If ur friends did then it was put in by someone.

[jmc6000]

4.3s did not come with roller rockers from the factory till about 2004.

[suzukirm80]

was it the 90-92 4.3's that had roller rockers? i have a buddie with a 91 and it is equipped with roller rockers.

[jimmyman1991]

it was after 91 because mine dont hav rollers, so prob 94 at least  and later then that

[F150TuffTruckman]

Hey, that sounds pretty good. Kind of sounds like a 305.

[hottrodder7574]

how big are the pipes?, iwant 3 in but im not sure if it will hurt proforamce( i cant spell)

[ozzy32090]

I have a 92 C1500 with V6 4.3L, in theory mine should sound the same as yours, do you think it would??? Otherwise nice vid, the truck sounds really good

[bigmasaquata1]

sounds great

[bradradar16]

sounds like my x/t

[wingsofdrkness]

Sounds really good

[mrfish1991]

i wish my S10 sounded like that...are you running true dual or just splitting it?

[jmc6000]

Just a stock Y-pipe and they are split at the muffler.

[Artyfil]

Where did you get another tailpipe that's parallel to the original one for the dual exhaust? I have a 94 jimmy and i was thinking of getting a dual for it, with the y-pipe. and where did you get the high flow cat? did you need to weld it in?

[jmc6000]

The tailpipes where done custom at an exhaust shop.  The highflow cat was bought at autozone.

[kreigsmann]

why did you buy a new cat?

just cut it off and keep it off!

all it does is create pressure for the engine

[jmc6000]

If you look at a couple of my comments earlier you will see there was a highflow cat installed instead of deleting it alltogther.  Plus the 4.3 tends to get a tad raspy with no cat at all.

[kreigsmann]

then get a larger muffler

a cat just causes damage to the engine in the long run

[90z28]

i hate the cats to but how do they damage the engine?

[buickgn1987]

your an idiot, cats dont cause damage to the engine, they help the engine with emissions you bloody imbisile

[kreigsmann]

bloody imbisile? you must be a queer brit

how can helping emissions help the engine?

it damages the engine by getting clogged

deal with the truth fag

[buickgn1987]

mmmk whatever you say el ca piton

[kreigsmann]

....wow

[Z2theONA]

fuck the environment, it's not worth the extra back pressure a cat creates /sarcasm

[kreigsmann]

...............

[89wagoneer]

in no way what so ever does a cat hurt an engine its doesnt clog it up its set to run at that amount of back pressure alltho removing them does add hp in most cases if you dont increase the air into the motor it doesnt run properly and can hurt the motor

learn the truth fags!

[kreigsmann]

back pressure causes too much pressure in the piston cycle that theres to be no pressure at all

THATS how it damages the engine and THATS how it decreases HP.

....bitch....

do you have a 89 wagoneer?

are those v8s?

or the jeep 4.0 v6

[89wagoneer]

when the motor is designed to have backpressure having it cannon hurt it
