i blew a gasket in my aftermarket 4-2-1 header set. the gasket is between 4 and 2. i took it to a shop and they said i need the gasket from the company, im wondering if i do that it might just blow again. anyone know any highperformance gaskets that i could order online? keep in mind it is between the 4 and 2 so it'd have to have 2holes in it, with 3 for screws. any help is appreciated, im frustrated enough to just replace the headers if i have to but that just doesnt make any sense.
