I've heard a lot of people say otherwise on their Pacesetter headers. Many are not happy with the quality and the fit n finish of their headers. There's a reason these headers are 1/2 the price of all LTs and cheaper then most shorties. Personal, headers on our car is something you want to do once. I'd go with a quality Stainless LT and be done with it. Yes, they cost more but at least you won't have to worry about quality.
