swappers, what did you do for exhaust? Options

[brianforster]

now we all know that 3" is pretty standard for all our swappers.

what did you do for exhaust? custom from a shop close to you? make it on your own?

whatd the shop quote you?

how much was it if you did it yourself?

looking for general price quotes here, trying to plan out the finishing touches of the swap and the only exhaust shop i called said "theyd have to look at the car".

to cut down on costs i think im going to buy my own cat and muffler from summit (43 bucks for cat, 18 bucks for muffler, summit turbo muflers for the win!) i just wanna know if you guys have any idea what it will cost. i already have a downpipe.

i tried searching, but everyone just says they have 3" exhaust, not where or how they aquired it, and since they are all custom, was wondering what everyone did for it!

thanks as always

The addition of the turbo doesn't effect the basic principles of exhaust flow - it only makes it more important since a poorly flowing exhaust will hinder the turbos ability to make boost.

Looking back at the previous posts:

with a turbo setup, the best exhaust is no exhaust.

Right, because a 6" long exhaust means the gases are instantly out of the way. No worry about pulses or scavaging or back pressure. Though no back pressure will hinder performance before the turbo spools up.

The next best thing to having no exhaust is having an MR2 - thier full exhaust is as long as our cat backs. That or an exhaust big enough to seem like there no exhuast - like a 12" diameter! I have no idea where anyone will find a muffler to fit it though.

Can you post some dyno graphs for 2.5" versus 3"? I spent a few minutes on google and only found debates on the DSM, 200/240, SRT, and Volvo clubs on the same subject! I guess this makes 6gc a real club!!!!!!
