I just purchased my Evo 9 and it has a buschur racing 3" turboback with HFC installed. The downpipe leaks at the O2 housing because they do not incorporate a donut gasket connection in their design.

I thought now would be a good time to upgrade o2 housings so I just changed the stock O2 housing to an invidia housing last night and realized that the buschur downpipe would not fit that housing.

To fix my problem I am considering purchasing an Invidia downpipe and mating it with the Buschur cat/catback. Does anyone know if the Invidia downpipe will mate with the buschur racing cat? it has the two bolt flange for the downpipe, so i am guessing it should work.

Thanks!

 

There is a gasket that will work. 6 dollars at advanced auto..

You wanna search for it or you want tbe spoon. Tip: I posted in the thread

Probably should say😜


Those are standard fitment pieces do mix and match
