I have an 04' mini with an OBX header. The donut blew out and I don't know the OBX number or the size of the donut (I.D/O.D).

HELP!

 

I have this header in my room, just recieved it in the mail yesterday. I have to go measure it and then i'll be right back with the full dimensions of the "donut"

 

Small Side- I.D. 2 3/8" O.D. 2 1/2" Wall thinkness 1/16"

Large Side- I.D. 2 5/16" O.D. 3 1/16" Wall thinkness 1/16" (same obvously)

Flange- 7/16" thick I.D. 2 5/8" on small side. beveled side is 2 13/16"


I was wondering if you have your stock cat welded to it or if you have a test pipe on it? And if so do you need any bends in a test pipe to get from the OBX header to the cat-back portion of the exhaust?

Thanks in advance!

This maybe old, but it is archived for a reason. My OBX header has been in service 10 + years and I'm sure the donut would still be in good shape if the guy who replaced my CAT hadn't tightened down the bolts the way he did.
I am on the hunt for the elusive OBX header donut. Yes I have been to their WEB site and no it isn't listed. Does anyone know where to get one or one that will work?

 

Lifer, yeah I'm addicted to MINI's.
