Jeff,
Everyone you ask is gonna have their own opinion. You asked what's the best bang for the buck in performance but you say it's your dad's car....would he mind a louder exhaust, stiffer ride, a roar from an air intake system when he puts his foot down?
The first page of this forum is loaded with aftermarket dealers. I haven't heard of a bad one, but some are a little cheaper than others and some are faster than other as far as filling your order. We could all start naming the one's we've dealt with, but then you'd be stuck with a large list of names.
On the top of this page and in all the forums, there's a "SEARCH" button. Do a search on "exhaust" or other mods and see what some of the PT owners have been saying about their parts.
Good Luck.
