A lot of options man. I always use corsa exhaust. Take a look at their systems. You will not gain much power from exhaust though. You could do a FAST intake, and also a CAI, which would probably allow you to see and feel some power gain. The brand for the CAI is up to you. I personally like K&N, but a lot of people have bought and loved CAI Inc., so it is really up to you on that. There are so many brands for exhaust and CAI's that you just have to chose what you think is best.
