Exhaust for turbo

[H22AdelSol]

If i get 3" piping for my turbo setup does it matter what muffler i use or is there mufflers designed for it. basically i cant remember if the inlet on the muffler 2.5-2.5 then a big tip. wouldnt having a muffler with a smaller input then the piping ruin the whole point of having big piping?

doesn't ruin it completely- but it certainly makes a difference- that's the same as pinched the end of the straw while you're blowing through it-

you'll want a straight-through perforated core muffler if youre running a turbo. you want the muffler inlet to be the same size as the rest of the exhaust for the least amount of back pressure. you can go big on the exhaust just make sure not to go too big on the intake plumbing as that can lead to turbo lag. good luck

yeah for once i agree with a n00b B)

so with a turbo back pressure doesnt matter? Also would there be much of a gain in going straight pipe?

with a turbo you want as little restriction as possible
if it was legal id say run an open dump

 

[Slammed90Lude]

yeah dude, backpressure is the enemy- you're trying to create as little resctriction in the exhaust gases past the turbine as possible

get soemting generic......like flowmaster with an resonator.

3" all the way.

magnaflow, dynamax, etc all make 3" mufflers under $100
