Thread: Downpipe Gasket???

Correct I have those covered. I looked at my post and I didn't explain well. I'm looking for the gasket that sits between the rear header flexpipe and the U shaped downpipe. It came with a coupler to attach them together but I'm assuming I need a gasket. It measures almost 3 inches inside diameter.

I didn't use a gasket and I think it is fine (2 weeks ago). If i thought it were leaking there I would try the copper rtv for exhaust (used thit at the 3" slip connections and the egr tube). Did you have issues with the 02 clearing? I want to hook up my wide-band (installed an extra bung with only 1/2" clearance) but with the bung provided it does not clear in my car.
