get a new cat back exhaust. look for techtonics they are really nice. do not make my mistake and and go to muffler brothers and just get the resonator deleted and a "flow-master"("" means a knockoff) it sound ok but ive had nothing but problems trying to ge it to sit right.
for a cold air intake just look around u will find them. they just bolt on. try abd or neuspeed. if ur broke like me just drill a bunch of holes in ur factory box and that will get the job done. u will here the difference.
handling= new stiff shocks(koni adjustable) race springs, poly bushings, sway bars, strut tower bar. wider wheels and tires. wheel spacers for looks. makes stance wider. eurosport has a lower tie bar.
that will get u something to look for.
