Performance Mods for Sedan!?

[miniboon]

So I've been looking around, and it seems like most of the parts say they are for the liftback....does it make a difference?? I'd really like to start with some basics, just a CAI, Cat-back, etc. Will parts that say liftback fit the sedan? also, any links to good aftermarket part sites? (ive checked the sponsors)

TIA

suspension parts are interchangeable, so are CAI. but exhaust are different.
