Frequently Asked Questions

Q: Will this head pipe work with my stock silencer?
A: Yes, the FMF Gold Series Fatty Head Pipe is designed to mate perfectly with your factory silencer, though pairing it with an FMF silencer will yield the best performance results.

Q: How does the Tru-Flo stamping process benefit my motorcycle?
A: Tru-Flo stamping creates smoother, more consistent curves in the steel. This provides optimum exhaust flow characteristics, improving your 2-stroke's power delivery and throttle response.

Expert Pro-Tip: Whenever installing a new expansion chamber, always replace the exhaust O-rings at the cylinder exhaust port. Old O-rings compress and dry out over time, leading to messy leaks that rob your engine of crucial backpressure. Lightly coat the new O-rings in high-temp grease to help them seat properly during installation.
