I just installed a berk 63.5mm hfc, I didn't replace the donut gasket and now have a exhaust leak at the flange. Does anyone know if a new oem donut will work?
Seems like the flange opening is a little deeper on the Berk cat. Didn't see a listing for a berk donut gasket in evasive motorsports Web site. Anyone run into this?

 

Oem will work fine. I ordered one when i replaced my cat for the berk 63.5mm HFC because i was scared the old one would be destroyed but it came out no problem and i used it.

 

Thanks. I'll get a new oem donut.
