Re 20V avant muffler

[n-engelbert at terrans.net]

I don't know how much this adds, but I took the exhaust off my avant with
108k at the time, and transplanted it over to a sedan with no issues. 
They looked the same, in that I couldn't see any differences in them. 
But, I didn't look very closely either.

I swapped the entire cat-back system between cars, and I have pictures of
the avant exhaust somewhere if you want them, Mike.

My vote, however, is that the exhaust is the same between the 20v sedans
and avants, and possibly more.
