After reading a couple of reviews before buying the gasket a couple of tips the first is a repeat. ORDER 2 they come ONE to a package. OK! Now to install the gasket 1) look at the gasket carefully there is one spot in the gasket that is slightly weaker looking than the rest of the gasket. 2 Place the weak spot in the port first then work the rest of the gasket evenly into the port and you FINISHED. 30 seconds at the most. Do this and you can smile when you hear your friends tell what a pain it was or how how many they destroyed before they FINALLY got one in.
Easy to install, once you get the stock tapered gaskets out, which were surprisingly tenacious. These gaskets can be fit with your fingers, just walk them carefully around the port, and gently slip them in place. So far, they work great, and I detect no leaks.
I like these better then the earlier woven wire EVO gaskets.... a lil more of a task to get them in the exhaust port without ruining the gasket ...BUT a better seal and last longer which means better performance, less problems and more time to play... a great piece!
