CAI are a pain to maintain, unless u are used to removing the bumper every so often; the typhoon will just suck in hot air. you can instead put a K&N or green drop-in filter and remove the intake panels.
save money, for example a fidanza flywheel or titanium twin-canister exhaust or a new set of tires/rims. but hey, that's just my $0.2.

 

Evo,

I am very happy with the greddy sp2. This is the first time I've modified exhaust so I really can't compare with anything else but for me, it is doing the trick. I called every auto shop in town and finally found a place that could get it. I think it was around $650 CDN but I could be a little off. I am so tired of expensive parts coming from the U.S. and am glad I could just buy it locally.

Good luck with your search and choice. I think the Racing Beat exhaust is probably owned by more people here and gets great reviews.
