After installing my Berk test pipe, I have noticed that it is slightly shorter than the OEM cat, and is causing the leak on the donut gasket (which I replaced without resolution). Exhaust smell in the car is driving me crazy.

I am looking for Cat-back Exhaust Gaskets (2.36", 3-bolt) that I could put behind the test pipe to push it against the donut gasket, I need 3 gaskets (one came with my berk) to "bridge" that gap, does anyone knows a place or have some for sale?

Thanks.

Look at the design, Are you sure adding material to the opposite side will help your situation?

In my experience what did work was cut your old donut gasket in half to make about a 3/8" spacer or whatever you need to bridge the gap

Due to the spring bolt design, they don't provide enough compression to pull the entire exhaust forward to seal at the donut gasket, there are few ways around it but the easiest and cheapest is to put a spacer (in my case few gaskets) behind the cat to relieve that tension from the muffler and cat-back hangers which are pulling the cat backwards, breaking the seal at the donut gasket.

Another way is to add a 3-bolt flange behind the cat, but I don't want to hack my perfectly good cat, which might be useful in the future.

Any ideas where to source the gaskets, or a flange locally?
