Hi everyone, I have a problem with my exhaust again. I recently purchased a new apexi noir exhuast and new magnaflow cat. I put it on and the flex area between the strup shorty header and magnaflow cat is leaking and its making my smooth ep3 sound like a ups delivery truck. Does anyone know what size donut gasket or whatever goes on the end a strup shorty header to a magnaflow cat? The gasket that came with the magnaflow cat does not fit and that is the same as the oem gasket which is too small .Please help, thank you

Look for (maybe) an RSX Type-S or TSX gasket. The kid who's got my EP3 now had to use a TSX gasket to fix the leak between the JDM CTR-spec catback and Type-S cat I had on the car.
(different gasket location, I know, but it's a route worth checking)
