Electric Exhaust Cutout Valve Kit — Adjustable, Stainless, 51–76 mm

A pair of electrically actuated exhaust cutout valves with an adjustable valve angle, so you can open the exhaust up on demand and close it again for the drive home. Stainless steel throughout.

What you get

• Sold as a pair — for a twin-exit system.
• Electric actuation with adjustable angle — not just fully open or fully shut.
• Stainless steel — the right material for something living under a car through winter.
• Four pipe sizes — 51, 63, 70 and 76 mm.

Worth knowing before you buy

This is the most involved product in the shop and we would rather be straight about it. Measure your existing pipe outer diameter before ordering — the sizes do not adapt. Fitting requires cutting and welding into the exhaust, so it is a workshop job unless you weld. And in most Canadian provinces, a valve that bypasses the muffler is not street legal and will fail a safety inspection. Plenty of people fit these for track use. Know which you are buying it for.
