Frequently Asked Questions

Q: Will I need to re-jet my carburetor after installing this pipe?
A: Yes. Whenever you improve the exhaust flow on a 2-stroke engine, you must adjust your jetting to match the new airflow to prevent a lean condition and ensure optimal performance.

Q: Is this pipe more durable than the stock exhaust?
A: Absolutely. The 19-gauge steel construction is significantly stronger than the standard materials used in many OEM pipes, making it much more resistant to trail damage and dings.

Expert Pro-Tip: Always replace your exhaust O-rings and gaskets when installing a new pipe. Old, flattened seals will leak exhaust gases, leading to a loss in bottom-end power and unsightly oil spray around your cylinder head connection.
