Muffler baffle insert for RYCA Sportster exhaust. Can be packed with fiberglass for a quieter exhaust. A variety of stainless steel end caps (included) adjust the amount of exhaust flow, allowing you to tune the sound and performance. Use the open end cap for increased horsepower and sound. Use the more restrictive end cap for more low end torque and muffled sound.
[Note: if purchased separately from the Sportster exhaust, there are a few steps to make the baffle fit into the body of the exhaust correctly. Please see the video guide.]
