There is no warranty on exhaust pipes and mufflers with regard to any discoloration. Discoloration (bluing) is the result of tuning characteristics, cam timing, carburetor jetting, overheating, etc., and is not caused by defective manufacturing. See the CHEMS/LUBES section for products that will help prevent or remove bluing.

Installation of a new exhaust system may change your motorcycles fuel-air mixture requirements. Please consult the exhaust manufacturer directly with questions regarding any modifications that may need to be made during, or after, installing their product. If a jet kit or fuel processor is recommended, see the FUEL/INTAKE section.

My favorite exhaust
I love this exhaust it is well thought out and high quality , it also offers a style of side by side which I prefer , then to top it off is an American made product , I had quite a few sets and very satisfied enough not to look further for a different brand , I will add I had to modify because of my bike choice but I do like to fabricate. On my standard Harley’s they fit flawlessly
