Our VR6 test pipe is the perfect fit! Removing the catalytic converter on a VR6 results in a sharper exhaust note and better flow. Horsepower gains of 3-5hp can be had in the upper RPM ranges while low end torque is not sacrificed. Our test pipes are CNC mandrel bent and TIG welded for a perfect fit every time. A simple mod with instant results.

Our VR6 test pipes are available reduced to fit the stock sleeve clamp, or 2.5" through to fit 2.5" cat-backs. A fresh OEM gasket & replacement hardware is included with every pipe. Though based on the mk3 VR6 cat, our test pipes fit a wide range of VWs. Check out the application guide below to choose the correct test pipe for your vehicle.

Power Gains:

Let's face it, removing the cat isn't going to be like a shot of nitrous. However, we find this modification to be very worthwhile. Years ago we did a back to back test and found peak gains of 5whp and 6wtq on a normally modified all-motor VR6. Those numbers are certainly worthwhile in a detailed all-motor build. Even larger power gains can be had on supercharged or turbocharged car. Of course, individual power gains depend on the condition of the catalytic converter removed, the exhaust system used, and the condition of the motor. We wouldn't build them if they didn't work.

The Sound:

The resulting sound of a test pipe also depends on the exhaust system used. Overall, adding a test pipe increases the volume of the exhaust note while also providing a much sharper sound. For example, when using a Magnaflow 2.25" cat-back exhaust system the volume of the exhaust note increases some at idle and cruising while becoming significantly louder at higher RPMs. Idle and low-load cruising attract little additional attention to the vehicle. High-revs and aggressive driving are obviously louder activities. Inside the car all low rpm 'drone' disappears. The exhaust note can be heard, but does not drown out the radio or conversation.
