i need new exhaust from y pipe to muffler any suggestions im running a turbo at 15 psi please help tnaks to all

 

Just find an OE spec cat, and get either a Budget or Cattman b-pipe depending on your budget.

 

You are running "a turbo at 15psi" and don't know anything about exhaust?

 

you probably should have thought about exhaust first, huh?

on the off chance there's any merit to this thread... 15psi might justify 3" piping, i think there are some threads on it in the fi forum.

 

3" custom piping alllllllllllll the way to the tail pipe

 

Its Not That I Dont Know About Exhaust I Just Wanted Othe Peoples Opinions On What I Should Go With

 

You need 3 inch. Do you have any pics/videos/dyno of that beast?

 

If you are running ******* 15psi I would hope that you would run at least 3 inch diameter piping. You are on reverse Y setup right?

If you don't want to sound totally nuts try a nice long resonator and an Apexi WS (turbo-spec) muffler at the end. Since the setup is pretty one-off anyway on the turbo you are going might as well run a custom setup, most cat backs are not even 2.5 inside diameter.
