[Kmart2352]

[codydubb]

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

bigger pipe deeper sound

[Kmart2352]

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

[Kmart2352]

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

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?

3 inch super 44's sound pretty mean

[mooseknuckles]

what are true duals?

[bbbc10]

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....

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

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

[bigblock73]

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

[THE "10" SILVERADO]

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..

[bbbc10]

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....

[maynardtruckin]

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.

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

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

[maynardtruckin]

I didnt notice any loss personaly on my dyno runs.

[Kmart2352]

How do you think corsa would sound true duals?

[codydubb]

Last i checked all engines need back pressure
