Hey all...just wondering because I'm about to install a Downpipe on my car. What's the diameter of the factory DP donut gasket? Is there anything special about it or can I just run down to my local autostore and pick up a universal one in the same diameter? Thanks!

 

I installed my turbo back last week and I just reused the factory donut gasket.

 

reused my stocker after the dp install on mine.
