About Cometic

Cometic Gasket manufactures multi-layer steel head gaskets and complete gasket kits in Concord, Ohio. On a built V-twin running higher compression or a big-bore kit, the MLS head gasket is what keeps the top end sealed — which is why Cometic is the default spec on so many engine builds.

A proper seal at the intake and exhaust ports is crucial for any V-twin, and this Cometic gasket delivers. Engineered to withstand the high heat and pressure of your motorcycle's engine, it provides a reliable seal for both intake and exhaust manifolds. This gasket is a direct replacement for OE #27002-89, making it a straightforward upgrade for many Harley-Davidson and Indian Motorcycle applications.

It works as advertised. The only issue with this one is there is no top ring, so you have to be careful when its placed in the exhaust, you have to keep it from sliding into the exhaust.

Excellent quality and easy install

I have never removed mufflers from a motorcycle before. So as I planned the install of new slip-ons, I kept reading that I should replace the gaskets. I really wasn't sure where I would be installing a muffler gasket, because I was looking for a gasket like you place on a car when you replace/repair the exhaust system. I actually had to get someone to show me the exploded view of the exhaust system of my bike and show me the gaskets and how they fit with the slip-ons, before I had an understanding. I'm glad I purchased these gaskets. The old gaskets started breaking into pieces as I tried to remove them. I finally gave up with their removal and slipped the new gaskets on the exhaust pipe, slid the new slip-ons right on and tightened the clamp and the bolts. Installation was complete and I think the gaskets made the install quick and easy. They appear to be great quality and I recommend them! Only time will tell how they hold up.

Pair of muffler gaskets.

They come as a pair and worked perfectly for putting on my Cobra Neighbor Hater mufflers on my 2019 Deluxe M8 107.
