Help me out here...

I'm trying to really piss my sister off, and I need your help. She is dead-set on me not touching her car. So, for her birthday I would like to toss a Header, Cat-Back Exhaust, Body-Kit, Z3 Fenders, and an aftermarket Hood on it. Now, the question is, do they even make such things for the Sunfire? lol If so hook me up with some places that may sell such items.

www.highrevmotorsports.com that should help you out..

pacesetterexhaust.com has headers for the 1995-2002 2.2l sunfire black $224.95 and polished for $334.95
mbrp.com has cat-back systems for $566 for 2003.

what exactly is the point of cat-back systems? wont a flowmaster minus catalytic converter do the same thing?
