Frequently Asked Questions

Q: Will this FMF Fatty pipe work with the stock mini silencer?
A: Yes, the FMF Gold Series Fatty pipe is designed to connect seamlessly to the stock OEM silencer, though pairing it with a matching FMF silencer will optimize overall performance.

Q: Does this expansion chamber require carburetor jetting adjustments?
A: Upgrading to a high-performance expansion chamber alters exhaust flow dynamics. We always recommend checking your jetting to ensure crisp throttle response across varying temperatures and tracks.

Expert Pro-Tip: Always use brand new O-rings and high-temp silicone sealant at the exhaust spigot during installation to prevent carbon leaks and premature wear on the header flange.
