Well if you get the entire cat back and get a high flow cat as well, then I'd say you could see up to 10-12hp. Companies always advertise higher gains, but often that's due to the fact that they're testing the exhausts out on a fuilly built up engine. So if you've got a stock engine, expect to get a little lower result in performance.

Really? They still leak even if you get a different set of gaskets like Feel Pro's? I know I've read on different places that the RKSport headers for the 3.8 had alot of issues with them. But that they fixed them and now if you bought the newer ones they should work fine. Not sure if it's true as I haven't had any experience working on the 3.8. But that's just from what I've read.

putting a different set of gaskets on would pry be fine.. but my buddy justin had em on his 96 bird and he had a few problems with leaking, he finally just got pissed and traded it in for a talon..
