Don't do it your self unless you're an expert. Otherwise you will have it too loud, makes noises when you don't want it and you'll spend more money trying to fix and change it. Look at Micro Image for some ideas or even a full exhaust from them. Just so you know, theres very little you can do to actually improve "performance". The tuning, which you'll have to get a fuel controller to fix, is the down fall for any improvement. Just keep that in mind.

I did notice a large change in MPG after changing the stock air filter though.
