Frequently Asked Questions
Q: Why are the O-rings green?
A: The green color indicates they are made of Viton® rubber, which has a much higher temperature rating and better chemical resistance than standard black rubber O-rings.
Q: Does this kit include the springs for the cylinder to the pipe?
A: Yes, the kit includes the necessary exhaust springs to securely mount your expansion chamber to the cylinder flange.
Q: How often should I replace my exhaust hardware?
A: For racing applications, we recommend replacing these seals every time you remove your pipe for maintenance or if you notice any “spooge” leaking from the manifold.
