I had my full exhaust aluminized and then coated with HTC. Voala less heat more power and no rust. Even where it was welded they coated. I had the shop show me different types of mufflers like borla, edelbrock, and dynomax and to tell you the truth they seemed cheaply made. The ones I really liked other than the flows where the polished edelbrocks.
