What is the QTEC actuator for?

The QTEC actuator is an electric motor that controls the butterfly valve inside the Y-pipe. This allows you to open or close the exhaust flow remotely, typically with a switch inside your vehicle's cabin.

What kind of installation does this Y-pipe require?

This is a weld-on Y-pipe. It requires cutting into your existing exhaust system and welding this piece into place. Professional installation is recommended if you are not experienced with welding.

Can this be used on any vehicle?

This Y-pipe has a 3-inch diameter and is designed for performance applications. You will need to ensure it fits your specific exhaust system layout and that the 3-inch diameter is appropriate for your vehicle's needs. It is not CARB approved and cannot be shipped to California.

Product Details

This QTP 3-inch Y-pipe features a weld-on design, meaning you'll need to cut into your existing exhaust system and weld this piece in place to integrate it. It's built to give you control over your exhaust flow, allowing you to switch between a quieter, more restricted path and a wide-open exhaust note. The QTEC part of the name refers to the electric actuator that controls the butterfly valve inside the Y-pipe, letting you adjust the exhaust flow with a switch inside your cabin.

The Y-pipe is constructed from durable steel, ready to handle the heat and vibration of your exhaust system. Its 3-inch diameter is suitable for many performance applications where increased exhaust flow is desired. By opening the valve, you reduce backpressure, which can lead to improved throttle response and a more aggressive exhaust sound. When closed, it routes exhaust through the muffler for a more subdued tone.

Keep in mind that this part is not CARB approved and cannot be shipped to California. You'll also want to plan for the installation, which involves cutting and welding. If you're looking to tune your exhaust sound and performance on demand, this Y-pipe offers a straightforward way to achieve it.
