well, especially if its is the factory single exhaust, i reccomend a better flowing dual three inch or beter, especially with a turbo, if u cant afford it and can stand the volume and sound, then u can run it straight and still get better performance

A turbo does a rather good job of chopping up the exhaust pulses, which is all a muffler does anyway.

just hack it off and run a 45 or a 90 degree adapter out the side it cost me 12 bucksto do mine i think.i thinkyou will be way more happy without the muffler.it will also sound twice as mean.mine even passed emissions like that.so i know it dont effect the clean burning part of it i think it would make it burn cleaner.

i bought mine at napa autozone also carries it about any parts store will.or you can go into an exhaust shop and have them cut you a piece they could even expand it for you so it just slips right in then throw 2 clamps on it or weld it instead of buying adapters.just a thought.
