I just got an 05 and the first mod im going to do is a catback exhaust. I dont know what brand to go with or if there is any difference between them. The prices sure as hell suggest that there is. Any advice on some good brands or systems to go with would be appreciated. Also, how much hp gains should i expect from this upgrade?
i have the greddy catback and invidia downpipe, and it is awesome. that greddy system sound soooooo nice. not too loud, more of a drastic growl. its good stuff.
When my ex remarried last year, I celebrated by getting a Cobb turbo-back along with an AccessPort. Sound is clear, deep and authoratative, and the muffler tucks up very nicely. Just downloaded Cobb's revised maps last weekend & she runs like a scalded cat!
what about the sti exhaust with the uppipe and downpipe. what is the downpipe like in the sti.. thought about putting an full sti setup on my new wagon.
