QTP 400117B 3in Black Electric Exhaust Cutout Kit

The QTP 400117B is a 3-inch electric exhaust cutout kit finished in black, designed to give you on-demand control over your vehicle's exhaust note. With the flip of a switch, you can bypass your muffler entirely for an aggressive, open exhaust sound, or close the valve to restore a quiet, factory-style tone for daily driving.

Key Features:

• 3-inch diameter cutout fits standard 3" exhaust piping
• Black finish for a clean, stealth appearance under the vehicle
• Electric actuator opens and closes the valve at the touch of a button
• Heavy-duty stainless steel construction for long-lasting durability and heat resistance
• Complete kit includes cutout, wiring harness, switch, and all necessary hardware
• Designed for straightforward installation — no permanent exhaust modifications required
• Compatible with both single and dual exhaust setups

QTP electric exhaust cutouts are a popular performance upgrade for muscle cars, trucks, and hot rods, allowing drivers to switch between stealth and performance exhaust tones without leaving their seat. The 400117B is built to QTP's proven quality standards and is designed for direct bolt-in installation on 3-inch exhaust systems.
