I am currently looking to buy an aftermarket exhaust manifold gasket because im changing my oil pan gasket from a small annoying leak, when i go to re-install my new header for my b20b i would like to replace the original beat up looking one. I've been searching online and all i keep coming across is the b18 gaskets from the tegs. All i want is something better than OEM can anyone shed some light for me please?

Something that wont restrict my header which is 2-1/2"

The b20s have the same head as the b18's I haven't never heard of a aftermarket exhaust gasket. I like the metal gaskets thats stock. When you put the gasket on the head look to see if any of it covers the exhaust ports and if so you can take a drimel and open it up to match the port but there usually so close I dont fool with it. You can get the gaskets from a local auto parts store. Hope that helps

Thanks for the reply "killer non vtec" i was just curious to see of anyone used a specific brand or prefered one from another thats all. Ordered one from Mr Gasket should be in this week.
