NOTES:
Not all products are legal for sale or use on pollution controlled vehicles. Check your local laws and the manufacturers information.

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 requirements. Please consult the exhaust manufacturer directly with questions regarding any modifications that my need to be made during, or after, installing their product. If a jet kit or fuel processor is recommended, the see the FUEL/INTAKE section

The Air Resources Board (ARB) does not permit the use of aftermarket emission-related parts that alter the air/fuel ratio of an emission-controlled vehicle. Due to these legal restrictions this part cannot be shipped to California.

Just what I was looking for

I spent a lot of time researching pipes for my 2015 Harley Street Bob. Just installed pipes today and they sound awesome! Low angry rumble, definitely better than the stock pipes. Installation was easy with the hardest part removing stock pipes.If your looking to upgrade and not spend a lot of money go with these pipes.
