Frequently Asked Questions

What does a torque valve do?

A torque valve manages exhaust backpressure by opening and closing based on engine load, helping maintain low-end torque on V-twin engines.

Will this fit my Harley or Indian?

Yes — this valve fits any V-twin with 1-3/4" exhaust pipe. Verify your current pipe diameter before ordering.

Is this a bolt-on part?

Yes. It installs inline with your exhaust system using standard clamps or welds, depending on your setup.

Do I need any additional hardware?

Check if your exhaust system uses band clamps or welded connections — you may need clamps or a professional install depending on your pipe style.
