I've used a couple of these gaskets. One I used twice. Perfect fit. Perfect quality. Grimmspeed is my go to for gaskets.

Same or even better than OEM
I used this with the 2.5”-3.0” Grimmspeed adapter running Cobb dp to Invidia Q300. No leak at all!

great quality, no exhaust leaks
This is a great product and I'd recommend to anyone making a 2.5" to 3" cat-back adaptation. When paired with the adapter braket everything fit well and sealed nicely even without exhaust sealant. My only issue is when used with the adapter plate braket, it moves one side of the exhaust out an additional 1/2 inch, which makes lining up dual exhaust tips difficult/not possible.
