What I intend on doing is getting a CAI, header, high-flow cat, custom 2.25" piping, and a high-flow muffler without the large tip so that it doesn't attract cops with the sound or looks. Plus, I want it to stay fairly quiet on the highway.
BTW, those silencers that you can get restrict the exhaust flow, therefore, they actually defeat the purpose of a high-flow exhaust. Unless you just want the exhaust for on the track, where you can remove the silencer.

 

ok so what is the cheapest catback system on the planet

 

dude ur horrible

cheapest catback on the planet or cheapest catback thats any good? they all fall about the same price (450-550). do some searcing on ebay and google and find what you want

 

OK, go with a turbo and custom piping, that way you'll save money because you don't have to get a header and you can also leave off the cat.

 

if you dont want to be loud and noticeable, then you want the Greddy EVO2 (which seems to be the favorite around here.). its nice and quiet, and makes a decent amount of power. on a sohc, it should give about 7-8hp. along with a CAI, header, and a high quality high-flow catalytic convertor, you should see nearly 15-25 hp(depending on the condition of your particular motor.).


cat-back-$450-$500
CAI-$120-$200
cat-$50-$150


these prices should get you some decent quality stuff. check out ebay.
