Thanks Tayles. Yeah one of the things i want to do is install a CAI, but that will only happen after ive saved some cash. In regards to the exhaust, there used to be a custom free-flow on it, but it made so much noise. So toyota replaced the muffler and tail pipe with a stock Sportivo exhaust, you can still hear the free-flow but it just doesnt make the same noise that it used to. So along with a CAI system, I want to change the end of the exhaust set-up.
