How is this exhaust cutout installed?

This is a bolt-on style cutout. You will need to cut a section out of your existing exhaust pipe and clamp this valve in place. It includes a dash-mounted switch for operation.

What is the difference between a single and dual cutout?

A single cutout, like this QTEC25, is designed for vehicles with a single exhaust pipe. A dual cutout would be used for vehicles with two separate exhaust pipes, allowing for independent control of each side.

Can this be used on any vehicle?

This cutout is designed for 2.5-inch exhaust pipes. While it can be adapted to many vehicles, it is not CARB approved and cannot be shipped to California due to emissions regulations.

Product Details

Constructed from strong 304 stainless steel, this QTP electric exhaust cutout valve is built to handle the heat and vibration of your exhaust system. It's designed to be bolted directly into your exhaust pipe, typically right after the catalytic converter and before the muffler. This allows you to electronically open a valve, bypassing your muffler entirely for a much louder, more aggressive exhaust note when you want it. When closed, it routes exhaust through your muffler for a quieter, more street-friendly sound.

The valve itself is operated by a simple electric switch that you can mount inside your cabin. With the flip of a switch, you can change your exhaust's sound profile from stealthy to wide-open. This particular model is a single cutout, meaning it's designed for a single exhaust pipe. The 2.5-inch diameter is a common size for many performance applications, but it's always a good idea to measure your exhaust pipe to ensure a proper fit before installation.

Keep in mind that this cutout is not CARB approved and cannot be shipped to California. It's a popular choice for those looking to easily switch between a more civilized exhaust note for daily driving and a loud, performance sound for track days or spirited driving.
