I purchased OEM Exhaust Gasket Part Number 44011AE010 which is supposed to go between the Rear Y-Pipe and the Muffler. The problem is that the Gasket seems to have a diameter of ~2" and for the pipe it looks more like 1 7/8". The gaasket bolt holes seem to line up however the seal is pretty bad. Anyone else run into this or have luck using a different gasket between the Y-Pipe and the muffler? I guess I can try to seal it up better with some RTV copper if all else fails.
