QTP Dual 3.5in Electric Valves / Wiring / 1 Toggle Switch / 2 SS 3.5in Cutouts

If you're looking to change up the sound of your exhaust on demand, these electric exhaust cutouts from QTP are a solid option. They let you switch between a quiet, muffled exhaust note and a wide-open, aggressive tone with the flip of a switch. This kit includes two 3.5-inch stainless steel cutouts, the necessary wiring, and a toggle switch to control them. It’s a popular way to get two distinct sounds from your exhaust system without needing to swap out mufflers or other components.

The cutouts themselves are made from stainless steel, which is a good choice for exhaust components because it holds up well against heat and corrosion. When the valves are closed, exhaust gases are routed through your existing muffler system, keeping things relatively quiet. When you open the valves, the exhaust gases bypass the muffler entirely, giving you a much louder and more direct sound. This setup is great for when you want to be discreet on the street but open up the sound for track days or just for fun.

This kit comes with everything you need to get them installed and working, including the wiring harness and a dash-mounted toggle switch. You'll need to figure out the best place to mount the switch in your cabin. Keep in mind that these cutouts are not CARB approved and cannot be shipped to California. Always refer to your local emissions regulations before installing.
