Good To Know

Q: Can I reuse my old muffler gasket? A: Muffler gaskets should not be reused once they have been compressed and heat cycled, so fit a fresh one whenever the joint is opened. A new gasket gives the best chance of a clean seal.

Q: How do I confirm this gasket fits my machine? A: Match the reference number 11009-3744 and your model and year against your parts listing before ordering. Checking the serial number and parts diagram helps confirm the right fit.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
