QTP Electric Exhaust Cutout

The QTP Electric Exhaust Cutout (also called an electric exhaust cut-out, exhaust dump or E-cut) is an electronically controlled valve. It installs ahead of the muffler and lets you switch between a quiet exhaust and a wide-open exhaust. Quick Time Performance says it invented the original electric exhaust cutout more than 20 years ago.

Key Features:

• Driver-controlled sound and flow: You can open or close the valve from inside the vehicle. You can also set it anywhere between fully closed and wide open.
• Machined aluminum construction: The valve body is CNC-machined 6061 aluminum with a precision-machined seal.
• Stainless steel internals: The butterfly plate and shaft are stainless steel.
• High-torque motor: A DC gear-drive motor with high-temperature steel gears drives the valve. A cast and machined aluminum cover protects the motor.
• Weather-resistant electrical system: The wiring harness is weatherproof. It uses interlocking weather-tight connectors with gold tips.
• Momentary toggle switch control: A switch mounted inside the vehicle operates the valve.
• American-made: QTP designs, manufactures and builds its cutouts in house in the USA.

Use it to keep the exhaust quiet for daily driving and open it up for the strip, the track or spirited driving. Depending on the variant, QTP offers the cutout as a valve, a kit or a system, for single or dual exhaust setups.
