2G o2 housing to Megan DP

[CiscoBite1Time]

I have a small exhaust leak where the DP mates to the stock o2 housing. I'm using a 2ply 2.5 gasket that came with my Megan exhaust setup. The gasket surface is clearly larger than the o2 surface. I have since bought some permatex copper spray and applied it on the gasket last night. I think that helped some but its still leaking a bit on the back side of the o2 housing.

I was researching this issue and found extreme psi has a 6 ply gasket for sale. Looks to be good quality. I think I may give it a shot. I need/want this car driving ASAP.

Is this a question or a heads up that Megan Racing has poor quality control?

Both my MR o2 housing and MR downpipe have flange issues. Big surprise. I no longer run the o2 housing because it's so bad.

So drive it then fix the exhaust leak

You could get the surface machined flat..
