Product Notes

Important Product Notes

Note: Please see U.S. EPA and your respective state and local regulations to confirm noise and emission compliance.

Important Exhaust Notes:

• Note: With any new exhaust, we recommend changes to carburetor jetting or use of an aftermarket fuel injection control module.

• There is no warranty on exhaust pipes and mufflers with regard to any discoloration. Blueing is caused by tuning characteristics, cam timing, carburetor jetting, overheating, etc. and is not caused by defective manufacturing. No refunds on exhaust pipes once motorcycle is started unless there's a manufacturer's defect.

These pipes are a great look on my 19 Road Glide Special. The sounds is a deep rich tone at idle, when you twist the throttle, it’s got a snappy feedback, at highway speeds cruising it’s a deep tone. When you get on it, it’s kind of poppy sounding but still sounds great. Once I pair it with headers, air intake and a fuel pack, this thing will scream. But for now skip one with stock headers and air intake, it’ll still wake your neighbors up !!! Great job S&S !!!!
