6G Celicas Forums

Autozone only has pipes and couplers so you can make one yourself.

If your wanting brand name you'll pay alot more (Injen, WeaponR, etc..), as far as the CAI goes, your going to have to put on together yourself, or use the kit from an accord (cant remember the year). There are a metric buttload of posts about CAI's and SRI's...all you have to do is search.
The header for the GT, you can get one from ebay (surewin) and its a pretty easy install. Although by doing so you delete your primary cat and may throw CEL's, and as far as a cat back, your best bet is to go custom, get a resonator and a muffler, then take it to a exhaust shop and have them do the piping. There are threads on all of this, use the search and the stickies.

Not much. SRI you're looking at MAYBE 2hp

CAI... 3 maybe 4

Not a lot at all. But it sounds good

how hard is it to install a new header and muffler?



ok cool.....I am looking to make the car louder cause its very quiet

I love my SRI but I only get the sexy noises at wide open throttle. Get a header from eBay so you can hear the sexy noises all throughout. As for muffler... don't buy anything from Pep Boys, Autozone, etc. Ask some members how they like their mufflers and what kind of tone they have before you make a choice. You don't wanna end up with a rattling bee on crack.

for the first thing, I would just get a short ram intake, or a cold air intake you can ebay them for very cheap (no super power gains) but they are cheap, look cool, and give your car a nice sound when revvvving
