355 True Duals
 

I just got a 355 put in my truck and I am looking to put true dual 3 inch mufflers and i just want to see what people have the best sound with, with duals?

Re: 355 True Duals
 

Flowmaster all the way.

Re: 355 True Duals
 

i also have a 355 i run dual 2.5 exhaust though hedman headers and flowmasters super 40's. truck sounds like a beast

Re: 355 True Duals
 

Mine is a 360 2 1/2" with super 40s sounds amazing. Why are you going 3 inch?

Re: 355 True Duals
 

the headers are 3 inch and i would like to keep it 3 inch all the way out

Re: 355 True Duals
 

3" flowmasters wth 40 series!!!!!!!!!!!!!!!!!!!! thats what i have on my truck an i also have a 355....it sounds sick!!!:metal::metal::metal:

Re: 355 True Duals
 

I am also going to put the pipes out in front of the wheels but at a different angle. Is the sound a very low tone or is it different than that?

Re: 355 True Duals
 

3 inch super 44's sound pretty mean

Re: 355 True Duals
 

what are true duals?

Re: 355 True Duals
 

its not that much of a low tone i say....u can feel my truck runing at my neighbors house...an when i get on my truck you can hear it from a pretty good damn distance....

Re: 355 True Duals
 

1 pipe/muffler per side from header/manifold all tha way back & out to tha tailpipe

Re: 355 True Duals
 

i have a 355 with a mild cam. long tube headers, 2.5 inch duals into super 44s turned down before the axle. sounds awesome

it had cherry bombs, sounded like poop

Re: 355 True Duals
 

running 3" pipe for a small block your going to loose a lot of bottom end power and at speed it will sound like its about to come apart

Im running 3" all the way out to be hind the wheels on my crew cab with a big block and hooker aero chamber mufflers. on the freeway people look back to see whats comming up beside them its LOUD

Re: 355 True Duals
 

I agree, 3" is waay too much pipe for your average small block.

Re: 355 True Duals
 

I'm running 2" true duals from the factory manifolds all the way back without cats and with some Flowmaster knockoffs (figured they would be temporary but I like them) and then down to 1.5 inch chrome tips in the back (for that old school look) it sounds really nice, not to loud but you can hear it from a ways away but doesn't drone in the cab.....hopefully will sound better when I install some new headers..

Re: 355 True Duals
 

well i dnt have ur average sb...its built for spray an it has no back pressure.....it really dnt sound like it gona come apart when i get on it....

Re: 355 True Duals
 

bigger pipe deeper sound

Re: 355 True Duals
 

The motor that I bought is ment for little back pressure and is ment to ment open.

Re: 355 True Duals
 

with the right muffler and a few bends in the pipe back pressure is not a problem. look at copper head 3" pipe all the way back.

Re: 355 True Duals
 

Copperhead had a 572, 3 inch pipes on a 350 will actually cost you some torque

Re: 355 True Duals
 

Running 355 with 2.5 and spintech Sportsman F Series,wakes up the neighbor's!!!!!!!!!!!!!!!!!!!!!!

Re: 355 True Duals
 

I didnt notice any loss personaly on my dyno runs.

Re: 355 True Duals
 

loud pipes save lives.

Re: 355 True Duals
 

They sure do

Re: 355 True Duals
 

How do you think corsa would sound true duals?

Re: 355 True Duals
 

Last i checked all engines need back pressure

Re: 355 True Duals
 

Re: 355 True Duals
 

I dunno about all that lol not something i would put on my vehicles

Re: 355 True Duals
 

Crackheads...and then they drive off like a couple of dumbasses and almost hit a car on the side street. I guess if you don't have a job then you have nothing better to do than to be annoying.

You don't need anything bigger than 2.5" on your 350. Anything bigger is a waste and will hurt you. The smaller dia. tubing keeps the hot gasses flowing faster than the bigger 3" dia will since you won't have enough exhaust pressure coming out of your engine to get the full effect of what a 3" system requires.

I have a 3" system behind a built 440 with Flowmaster Super 40's and it thunders. Way too loud if you ever want to listen to your radio.

Re: 355 True Duals
 

that can't be real?

Re: 355 True Duals
 

How about an x-pipe with whatever muffler of your choice? I think they make even stock engines sound aggressive. My pick would be Dynomax Ultra Flows
