So some lame-o really botched the Y pipe replacement job on my DII when the previous owner had it and I need to fix an exhaust leak between the Y pipe and intermediate muffler.
I have seen multiple sites with NOTHING there, the rave manual appears to have a flat gasket between the two and rovers north has a diagram of one with a donut type gasket, but when you go to the actual parts diagrams there is nothing listed!!
On atlantic british they sell a muffler kit with only one gasket for the tail pipe to muffler!
My car is leaking water at this union, so i know its leaking gas. What is supposed to be there?
If the rave shows a flat gasket but mine has a donut gasket, how accurate is the 18 ft/lb torque spec?

I do not believe there is a gasket between the Y-pipe and intermediate muffler. I had a leak there also. What I did to correct the leak issue.
Loosen and remove the flange, get a wire brush and clean both mating surfaces completely. Then, re-assemble, torquing the flange nuts, substantially. Be careful, not to snap or strip the bolts. This should do it for ya.

There is no gasket, because it works like a compression fitting. After cleaning the surfaces with fine sandpaper, it revealed bump at the pipe end (what looked like a manufacturing error). Smoothed it out with a file and sandpaper and my leak was gone. I guess the bump caused it never to seal properly.
