Bought multiple different sets of gaskets for my N54 powered E61. These were the right diameter for the stock exhaust flanges. Thickness was just right too. Half price of OE alternatives too!

Got these to use on downpipes on my N54 which fit and work perfectly. I got 3 sets before buying these that fit just right. Excellent.

Terrible!! I brought these cuz they were cheap. 1 ride and the left downpipe had an exhaust leak. So I replaced it with an fcp euro gasket and right after, the right downpipe starts leaking!! Then I had to order another gasket... it's my fault for buying these, but here's your warningThis is not a temporary fix by all means. Buy fcp euro gaskets!!

Used these to replace toasted OEM gaskets between the downpipes/midpipes on a BMW with an N54 engine. Fitment is fine and there are no leaks. I see no reason to pay OEM prices when these gaskets appear to work just as well and are a fraction of the price. It will be interesting to see how well they hold up over time but at this point I would not hesitate to buy them again.Update 10/2019 -- I had to change out the midpipe that these gaskets were used to seal, and to my great surprise the gaskets are still intact. I did not expect this because the stock BMW gaskets (which are ~ 3x the cost of these) would have completely disintegrated by this time.
