Diffuser discs are the key to tuning your SuperTrapp muffler for power, torque, or sound. Each disc adds a gap for exhaust gas and noise to escape. More discs means less backpressure, enhancing top-end power. Fewer discs means more backpressure, generally enhancing low-end torque and lowering noise.
These diffuser discs fit any of our SuperTrapp 5 Inch Disc Mufflers. Package of 12 discs.
