i know the basic mods, exhaust, cai, shifter. but wanted to know about headers and midpipes.
how hard would headers take to install in a 328?
what catback is the perfect balance between power, sound, price?
if i were to get a 328 could i install this http://www.turnermotorsport.com/html/detai...ID=jccaischrick

how hard and long would this take, and what about a chip or something?
