Street Slayer slip on system with CARBON muffler

Street Slayer slip ons are the hot new look for the R1. This system boosts power while giving your bike a richer sound, without being too loud.

Street Slayer Mount - This mounting style mounts much like our "GP" system. Much lower and forward than stock, near the right rider foot peg. Enjoy the same style benefits as our "GP" mount with a slightly lower dB level.
Available dB reducing muffler inserts: Stage 1 part # Q7
NOTE: This system may drag during track use at heavy lean angle.
NOTE: M4 Recommends re-flashing your stock ECU to unleash the full potential of all M4 products on the Yamaha R1.
