I installed a stromung catback, and now I have a exhaust leak where the cat and the catback meets.
The flanges are met at an angle, it looks like this:
I didn't get a donut gasket when I did the install, I'm guessing that's my problem.
Question: If I get the donut gasket installed, would it fix the leak? Even though the flanges don't mate up perfectly? Do I need to get some RTV sealant too?
And does anybody know if a 02 outback uses the same donut gasket as a 02 Impreza?
Thank you.
