Downpipe/O2 Housing gasket

[temfate]

Anyone know what gasket I need to match a Buschur racing 2.5" downpipe to a stock O2 housing?

I see Buschur racing lists a 2.5" gasket at their site but wanted to ask first and see if anyone knows if it'll work or if I need to custom make one.

Thanks.

Unless you've ported the o2 I would stick with the stock gasket so it will fit the o2 studs perfectly. If you chose to use a 2.5" gasket you must make sure it's center perfectly because 2.5" is not that far from the edge of a 1g o2 flange, I know this because I ported my 1g o2 to exactly 2.5".
