try the search button. I only say this bc its been proven 1 hojillion times that you wont lose anything to lack of back pressure with a 3" exhaust. the only thing you gain is facepalm status for sounding like a Jack@$$ with a stupid large exhaust. You dont really need a 3 inch exhaust untill you are turbo'd and even then a 2 1/2 would prob do you fine for a while. it really all depends on how much HP you want to have when you are done.
