when you shop for exhaust it is all about shopping for sound anyway. if you like the flowmaster sound, go for it. i would suggest you check out magnaflow before you decide. good fit and finish, nice tone, and the exhaustguys(members of the club) can give you a good deal on the kit.

headers, ceramic coated, 3inch collector, slip on cat = 350-68722 cost $450
they also list a chrome plated version for $350, but they would change colors and rust in no time.
for a cat you shoudl look on ebay. there are companies that well slip fit cats for hella cheap. don't get caught up in the "high flow" hype, it is a bunch of bs. the difference in flow from a $50 replacement piece and a $150 "high flow" piece is only around 4.5%, nto enough to make any power that you could ever feel.
