Exhaust ?s

Would 6 inch from the turbo back be to big?

Good luck gettting 6" downpipe in there. 4" is tight enough, 5" is a stretch.

Most of the guys in the know say that you don't need anything bigger than 4", unless you're running big twins and bigger fuel.

you wont get a 6 inch in there, you cant even get a 5inch in there unless you custom fit it (i mean bash it with a hammer untill it fits)

you can put a body lift on there and it does help, but like RD said yo dont need 6 inch, 5 inch is to big unless you have big twins

Bahh, to big!! Thats a matter of opinion. 6" is a litte much but if you have stolen a drainage culvert and want to use it as exaust I say why not. LOL. I run 5" and love it. I know I wont outgrow 5" and I would have with 4" in my opinion. One of the big mags did a test on different size exausts and came up with anything over 5" is a waste and for almost everyone 4" is fine. I figure if the turbo is 5" I'm gonna run 5". 2 cents.

there is no way you could fit a 6in downpipe it there, 4in is the biggest you can go. a 5in wouldn't even fit unless you banged it with a hammer.

The only way i could figure to run 5" is out the fenderwell along the outside of the frame, then up through the bed... At least thats how my twins are going when i build them.
