the one good thing about Pacesetter products is that they are pretty affordable ($186 is still a lot of money, but for a cat-back exhaust, it's not bad). i also like the way that the tips look (that yellow band is still pretty darn unique).
BUT, everwhere you find info on Pacesetter, you'll also find numerous complaints. the ones i hear the most are that the piping cracks after a few months, the seals never keep (even with good gaskets), and all the paint (yes, even that yellow band on the exhaust tips) flakes off a few months down the line.
now, flaking paint may not seem like much more than a minor annoyance, but imagine paying almost $200 for a header, and then watching a large crack develop in the piping a few months later (which of course, will mean that you'll have to replace it). i can't honestly say anything about Pacesetter stuff having never tried it personally, but search around and you'll find plenty of stories from people who have.
