Bikemaster Rubber Muffler Plug

Protects the exhaust system from water during pressure washing, keeps humidity from entering pipe as it cools down or prevents condensation inside the pipe during storage. Formulated to be stiff enough to not fall out but soft enough to be inserted into the pipe without causing damage.

• Small fits most 2-stroke applications
• Large fits most 4-stroke applications

Keep moisture out of your muffler during storage or washing. Soft for easy installation yet firm enough so it won’t fall out, choose small for two-stroke or large for four-stroke engines.
