Chevy Dually 454 Big Block True Dual Exhaust Flowmaster

[wtl1964]

in cold morning i see the gas make perfect smoke rings

[slowride55]

stick with the 50 man, she sounds sick. dont go 40 or 44 because they drone horrible and make you want to kill yourself. the 50 is a big block muffler, for this reason exactly :D

I always loved the 98 chevy 3500; bad ass!!!!

[maplemanz]

Diesel IS THE SHIT!!

[Jake45499]

@maplemanz Its a 454

[urdadddy1]

only the best sounding muffler ever !!!! especially with the bb !!!!

[GreaseMonkeyVIP]

Truck sounds nice tho man, do you have any other mods like ported tb, cam or anything? I just bought an 84 im gonna keep the 454 for this year as the diesel gets built and everything ready for resto... But I lucked out and found a very sweet truck thats super clean from an old friend I know takes very great care of everything he owns...

Are you running stock exhaust manifolds? Im gonna atleast get efi on this pig to keep some mileage lol Thanks for any help man Clean Clean Ride!!!!!

[init4thought]

Hey do you have the o2 sensors in the pipe still? I am removing my cats and putting straight pipe. But to do that I will not have the o2s in.. you think that will cause me issues?

[GreaseMonkeyVIP]

@init4thought

If you have 2 o2 sensor systems than run 1st sensor like normal in piping,

& what you want to do with 2nd sensor is get a pipe thats the same sizeish of the o2 bung, and have it be cut at a 45* angle and welded back together about 1-1/2" -2" away from the exhaust piping, and run again that distance so the o2 sensor will sit in pipe and be about 4" away from any direct flow.

That should keep codes away. Look around online they might have one you can just buy, CEL eliminator.

If i won the lottery, the first thing i'd buy is one of these 98 chevy 3500 4dr dually :)

[fordklr350]

dude nasty sounding truck i love that year dually!!

[dacotahhansel]

sounds great! you think it would sound good 3in with no cats??

[318dodgeN350camaro]

anit dissin you but true duals is stright pipe all of the way no mufflers no cats nothening but pipe sounds good tho looks good too

[aakv2001]

@318dodgeN350camaro Yeah, straight pipes are too loud with a 454, and It`s illegal in AZ so i need cats, and yeah it is true dual cause i have 2 cats and 2 muffles, fake duals is when you have just 1 cat or/and 1 muffler with 2 outlets.

Thanks for your wisdom tho.

[chevygearhead454]

@aakv2001 Its better to leave something on though, what none of these people realize is absolute straight pipe in a stock engines loses horsepower

[slowride55]

@318dodgeN350camaro Actually true duals is a pipe from each header/manifold, into a muffler, and out the back.

[318dodgeN350camaro]

@slowride55 my camaro was stright pipe from the manifolds back no muffler

[slowride55]

@318dodgeN350camaro Thats duals. True duals have mufflers.

[318dodgeN350camaro]

@slowride55 oh truck still sounds badass

[slowride55]

@318dodgeN350camaro Now that I agree with!

[kieffer1981]

@318dodgeN350camaro Wrong!!!

[vwmetal66]

hey man have you towed anything with this beast? If so how does it do? by the way badass dually

[jorgtrucking]

Nice Truck! I'm thinking about buying a truck with the 454, and no I'm not a tree hugger, but what does it get for mileage? I just want to know as much as possible before I buy. Thanks!

[ColtCobra2002]

ive got an 88 1/2 Extended Cab 454TBI with a TH400, and 4.11 rear end gear, it gets 7 on long trips

[adamsquires]

about 6 miles per gallon if you got it tunned up perfect. not for someone thats not going to work the horses

[90350Chevy]

LOL I am suprised that is the 50 series. umm if you want to see what a super 44 sounds like, come see my videos. I think mine is louder than yours lol. but im running headers and no cats.

[90350Chevy]

she sounds mean man! what series flows are you running?

[aakv2001]

Two 50 series flowmaster mufflers and 2 catalitic converters.

I used to have no catalitic converter but it was sooo loud and illegal in Arizona.

Sometimes i want to put 40 series or super 44 but i dont know. I think 50 series is good and loud enough. LOL. Thanks for the comments.

[MikeyLikesNike]

i live in az too and emissions suck. btw where did u get ur exhuast welded up cuz im lookin for a good shop that weld up a dual exhaust for me sometime in the future

[leafsrule16]
