I have a 2002 busa turbo. I have full stainless steel exhaust. I am looking into having the header, turbine housing, and down pipe ceramic coated by swaintech. I've heard some people claim the turbo can spool up a few hundred rpm faster similar to a turbo blanket. Some have claimed the turbo can spool up to 500 rpm faster and drop the temp of the pipes up to a couple hundred degrees. It is pricey though, but I would have some corrosion protection, the pipes are stainless steel and have minor rust. I really like the look of it but really want it for the performance aspects. From what ive gathered the coating from swain tech is the real deal not just for visual appearance. Any of you guys are gals have any input?
