There's a lot of if's in my life right now, but IF Speedy doesn't sell (2 weeks 0 calls) I may do the exhaust if I can find some money. If and when I do an exhaust on Speedy, i'll likley ceramic coat the header And I think I'll wrap it all the way to the collector.
Lime-Away works really good to clean the header, if your in england I don't think you can get it, but any lime, rust remover should work. Get some steel wool and rub the cleaner on the pipes with a rag then work it with the steel wool. Works very good.
