• Description

  The SA-4 head pipe is offered as an option to add to your SA-4 slip-on. If you have an existing SA-4 slip-on and are looking to add more power and replace your stock head pipe, this is it.

  • TIG welded 304 stainless steel.
  • Larger diameter than stock allowing more flow.
  • Maximum clearance and seamless fit.
  • Increased horsepower and torque gains.
  • Hand-crafted in the U.S.A.
  • Note: Not all models have a corresponding head pipe and are sold as full systems only. Bill's Pipes does not manufacture their head pipes to fit with any other aftermarket exhaust.
