Hi all, I have been a long time follower and have recently ran into a bit of trouble. I recently put on a Fujitsubo Cat-back exhaust. I am experiencing some exhaust leak from the cat to the B-midpipe.

I am wondering if I need a 3" donut gasket or can I use the stock one (or same size)? or do I even need one?

I bought it used so there was not one that came with the exhaust.

Your help would be greatly appreicated. Thank you.

you should reuse the stock gasket, unless it's falling apart. In which case just buy a replacement from your local dealer.

even thought the B-midpipe is 3" in diameter the stock sized gasket should be fine?
