Frequently Asked Questions

Q: How can I tell if my exhaust O-rings are bad?
A: Look for dark, oily buildup around the exhaust header pipe where it meets the cylinder. If you can physically wiggle the pipe at the connection point, it's definitely time to replace these seals.

Q: Should I use high-temp silicone with this kit?
A: A very thin smear of high-temp exhaust sealant can help hold the O-rings in place during assembly, but don't rely on silicone to bridge a large gap. The O-rings themselves should provide the primary seal.

Expert Pro-Tip: When installing the new O-rings, make sure the groove on the exhaust flange is perfectly clean and free of carbon buildup. Carbon is hard and will prevent the new O-ring from seating correctly, leading to a premature leak. A wire brush and some patience here are essential.
