These are good gaskets.The only problem i had was they are a tiny bit larger than the exhaust port on my honda vtx 1300 but you can push on them and work them in, or maybe put a little grease or something on them to make them go in better. They do work and make a good seal.
I bought 4 of them at DK's very low price compared to the same from Honda. I come to Dennis Kirk for most all things I need, as their prices are most always lower than other online or in town store's. Plus their shipping is usually very quick, Thanks DK.
