  • Performance increases are about 8 to 10 percent with the proper tune on the bike.
  • At idle, the motorbike is deep, boomy and full of character. Not only does the pipe look good, it is a wonderfully sounding experience for the rider.
  • Baffles come in a Wrapped version to make them a little quieter.
  • The inter core of the louvered baffle is 2 1/4"


  • Blueing and Discoloration are caused by Improper Tuning and will not be covered under Warranty
