i know when i installed my buschur down pipe wich if i remember sits flush against the o2 housing with no gasket or spring bolts.

my stock dough nut gasket or however you spell that was a pain to get out as well. but i just used a pair of needle nose plier and tore it to shreds pulling it out of there. eventually it comes out in pieces of course. but if u still need a gasket it would be smart to get a new one anyways. they aren't that expensive.

good luck!

I could not get a screwdriver into alignment with the dp gasket, so i just used a pair of pliers, one side on the gasket and one side inside the O2 housing and sorted of tilted and pulled at a few points around the gasket to get it out. BTW use anti-seize and wear gloves when using anti-seize.

I don't own one, but you're right it doesn't use a gasket at all. They don't leak either. David must have sprinkled some magic on that flange to keep it nice and tight.

My addidas pants still have some anti-seize on it that stuff gets stuck on everthing.

thats what i was saying that i personally have the buschur and it doesnt use the stock gasket

but when i went to remove the old gasket i used needle nose pliers or a set of dykes.

sorry if i worded it in a confusing manner

That gasket really is a bastard to get off. But this sounds like a good idea

All this talk about a donut gasket honestly guys I can't remember running into this. I did do my DP install about a year ago and I have a DC Sports DP. I have since removed that with very detail pictures and did not run into this gasket. In my mind the donut gasket is not the flat gasket that you normalls run into right? Your best bet would to find someone who has this DP installed

it looks exactly like a small metal donut. it goes in between the 02 housing and the downpipe.

You know what's funny is I just ordered this downpipe [Megan] and it came in the mail today. Haven't installed yet. I don't think I could help you because it'll be a week before I work on the car. I'll let you know if I run across the same problem with the gasket.

The donut gasket is there for a bit of flex between the turbo and exhaust system, it provides a pivot point that won't leak. Why doesn't the Buschur DP have a provision for the donut or a flex section?
