Title: Exhaust gaskets Post by: Glaserbeam on February 28, 2022, 02:03:38 PM I've seen two types of exhaust header-to-cylinder gaskets: copper gaskets with a circular cross-section, and other (aluminum?) with a square cross-section. Any preference?
Thanks. Title: Re: Exhaust gaskets Post by: Valker on February 28, 2022, 03:38:33 PM I've used them both with no detectable difference. They both crush. I thought that the round ones were a bit harder to remove than the others, but it could have been a lack of caffeine in me that one day.

Never knew or seen another variant on all metric's brands over the years. I use touch of high heat (red) silicone to assist in mounting.

Hope all is well for you out in Southern California. I've only used copper Honda gaskets, and when using the same exhaust I have not replaced them with no issues of leaks. Michael |
