2.5 inch from the turbo back for less than 400whp. 3 inch for 400+whp.

Thread done.

Its a perfect size. No need for a 3" right then.

Doesn't make sense to buy a 2.5" when you will eventually buy a 3"

Im curently running dezod 2.5" turbo exhaust but am switching to 3" Turbo-mafia exhaust when ever the hell it gets here.

I agree with just going straight to a 3" Exhaust. worst case you lose some torque we have too much mid range tq just spins the sh^t outta the tires on the street. the turbo should spool abit quicker i think definatly need 3" downpipe soon maybe few more psi wouldent hurt either.

Loose "some" torque....try a lot of torque.

from my understanding,you don't get alot of rasp with the exhaust of turbocharged cars because the turbocharger itself is the most restrictive part of the exhaust and it absorbs alot of the noise. so after the turbocharger, you want the exhaust to be as free flowwing as possible.

i am selling a different version of the dezod exhaust with a baffled muffler and a resonator in the mid pipe. Thing is so quiet and I love it.

It's a great exhaust with noticeable power gains from the stock exhaust while maintaining a more stealth sound.
