looking into buying a new itr catback exhaust from a dealer or a good used one from here...i have a 96 se(ls) and was wondering what year should the itr exhaust be to fit my se (ls)...also i need a cat and header so should i get the itr cat also or an aftermarket cat...what header will work best with this setup...? thanks...

p.s. purchase date around mid of feb..so if any one has one there about to sell heres your buyer come feb...thanks
