Control Your Sound. Control Your Exhaust.

Upgrade your 3-inch exhaust system with the Granatelli 313530 Single Oval Electronic Exhaust Cutout Kit.

Sizing & Fitment

This is an oval cutout for 3" oval exhaust tubing. Confirm your pipe is oval, not round, and check the outside dimensions at the mounting point before ordering. Running round pipe? See the 307530 round version. Running a true dual exhaust? Use one cutout per side, or choose the dual 313530D kit.

Where to Mount It

Mount the cutout at least 18 to 24 inches after the catalytic converters, and away from any O2 sensor. Aim the turndown toward the rocker panel, away from fuel and brake lines. For the best sound, mount it after the X-pipe or H-pipe.

Legal Note

Many states, including California, prohibit exhaust cutouts on vehicles driven on public roads. Keep the cutout closed on the street and open it only at sanctioned off-highway events. Never install a cutout upstream of a catalytic converter.

Frequently Asked Questions

Do I have to hold the switch?
No. The Smart-Chip one-touch rocker completes the valve's travel with one tap.

Can I install it myself?
Weld-in kits need welding equipment or a muffler shop.

What's the warranty?
90 days, with optional 1-, 2- or 3-year extended coverage available at checkout.

Will it add horsepower?
Opening the cutout reduces backpressure. Gains depend on your engine, headers and tune.
