So i have a 2004 g35 coupe I am thinking about getting a catless exhaust for it. I live in idaho so there are no emission laws. I am doing everything i can to keep it from sounding like a ricer. any suggestions for brands or types of exhaust systems that i should put on it. I already have an injen cold air intake and in the near future i will be installing twin turbos and all new internals, any ideas??

 

As always, if you plan on going FI upgrading components now is a waste of time.

 

Sage advice right there^^

You'll be changing a lot of things with FI so be patient and do it the right way, all at once.......
