ok, i have i think is an hks downpipe.. has the restrictive flex pipe that came w/ the engine, and had to purchase a used catback exhaust.. now. i am still searching but was told i need a flat gasket, got one locally 2 bolt, inside diamiter is 2 1/2" 's.. 1 side is completly flat, other side looks like a smaller circle gasket wich both is held together with a metal ring.. will this work or do i need to keep looking?

if anyone has any other sugestions.. please shoot away.. and maybe an online store to where i can purchase these from.
