Not as good as I thought they would be
Extremely difficult to get in exhaust port. I was not able to get in totally flush and installed the exhaust anyway to get them to pop into place.. After installing, the rubber in the gaskets melted and started to smoke within minutes of starting the bike. Some of that could be my fault as I exceeded the recommended torque specs. You would think a metal gasket could handle more torque though. I got the oem gaskets and had little issue getting them installed cleanly in the ports. Sealed right up without any leaks. This was with a Vance and Hines exhaust. I highly recommend going OEM instead of these. I had to install the exhaust twice because of these. I do not recommend.

I haven't been able to use them yet because the exhaust system I got with it didn't have any mounting hardware with it.

Great Gaskets for Danmoto Highway man
Easy to fit and install. My header gaskets were previously melted which was challenging but with a gasket solvent it took some time and they came out.<br /><br />One gasket came easy to install. The second had some spurring that I had to file down, but after 2 minutes, it fit easy peezy!
