It is a genuine gasket that is supplied directly from the original manufacturer for use with Honda engines commonly installed on lawn and garden equipment. This replacement gasket is used to create an air-tight seal for the muffler assembly, for correct location and uses make sure to check appropriate diagrams of your equipment. Over time the material may get compressed and crack eventually requiring replacement to maintain the proper seal. Please note this high quality composite material gasket is sold individually.

Removed old muffler and installed new one. Also installed the muffler gasket which was not on the old muffler. Gasket sealed the joint better and resulted in quieter operation.

Replaced muffler and gasket using information found on youtube.. I used plenty of penetrating oil (Blaster) so as not to break the bolts holding the old muffler on... It made the job a lot easier.

Tried to drill and easy-out old bolts unsuccessfully, had to drill out old muffler bolts completely. tapped boltholes out to M10X1.5 and inserted treaded bushing M6-1.0 X M10-1.5. cleaned up flange with emory wheel and installed new gasket, muffler, spark arrestor and plate, bolts, and muffler guard. Sounds and runs like a new mower. Not bat for a mower that's approx. 10 years old! Don't put em on the curb if the still run good folks! this route was much cheaper than a new mower!
