Anyone attempt this set-up?

 

im going to have mine done in a week or two...........using chambered mufflers from http://www.sweet-thunder.com

not really sure what lenght to use though, probably the shortest one 18" stainless

 

Yea thats where I found the mufflers. Which ones did you use?

 

i havent done it yet...........but im probably gonna order the 18" 304 stainless steel general use muffler, with a 3" diameter.

i have jethot longtubes..........so it will go to an Xpipe, then the mufflers, then dumps.

 

sounds good to me...do you think the 18" with the 3" inlet and outlet will fit?

 

im pretty sure it will..........look at this picture and you can see, those mufflers are about 12-14" im guessing...........so there seems to be room for 18" in the same location.

ill take pics when mine is done.

 

it does look that way...

 

anyone care to explain exactly how chambered mufflers work? My iroc had true duals with chambered mufflers when i bought it and i dont completly understand how the mufflers work. All i know is my car is LOUD and sounds awesome.

 

I got this reply from a guy at that web site:

2.5" diameter systems seem to be the most popular on Z-28's.

We're making them now and they will be ready the first of next week.

Call if we can be of more help.

I've asked if the 3" inlet will work as well...will post...

 

Anyone can tell me if there is HP gain from true duals or are they strickly cosmetic?

 

Yes there is a hp and torque gain through true duals rather than any other cat-back. It simply 'opens' up your exhaust so that there is less restriction, therefore producing more torque and hp in general.

Having headers causes a small loss in torque, but it is compensated...

 

it doesnt do much on a stock motor

but on a heads/cam or stroker, it can be an improvement.

 

i have the same idea.

^concepts.. the first one would work out better because its nearly impossible to route pipes over the drivers side of the axle. The mufflers you see will be 18" sweet thunder chambered.
