A: Yes, it is pounds lighter than the heavy stock OEM exhaust system, helping improve overall handling.

Expert Pro-Tip: When installing your new FMF slip-on muffler, ensure all header and mid-pipe connections are clean and free of debris. Use a high-temp silicone sealant at the slip joints if necessary to prevent exhaust leaks, and torque all mounting hardware evenly to factory specifications before your first ride.
