Exhaust Cutouts

An exhaust cutout gives you the best of both worlds — civilised cruising when closed, and unrestrained exhaust volume when you open it up. Whether you want to unleash the full voice of your engine at the track or enjoy a more aggressive note on the street, a cutout lets you bypass the rear muffler section on demand.

Our collection includes everything from simple manual block-off plates to fully electric, remote-controlled cutout kits. Key choices you'll make when building your setup:

  • Pipe diameter — match your existing exhaust tubing (common sizes: 2.25in, 2.5in, 3.0in).
  • Actuation — manual (wrench or cable-operated), electric (12V motorised valve), or boost/vacuum-actuated for turbo builds.
  • Material & construction — stainless steel bodies and flanges for corrosion resistance, with quality seal faces that won't leak when closed.
  • Motor & control — look for high-torque electric motors with wireless or hardwired controllers, and momentary or auto-stop actuation.
  • Hardware & gaskets — complete kits should include clamps, flange gaskets, and mounting hardware for a leak-free install.

Before ordering, measure your pipe OD at the desired cutout location and confirm you have adequate clearance for the assembly and motor. Most cutouts weld or clamp directly into a straight section of the mid-pipe; some replacement intermediate pipes with pre-welded cutouts are available for specific platforms.
