I ran across this on ebay while search for parts for a w210 E55 friend of mine, its a great SS x-pipe option to bypass 2nd pipes. It appears to be made by a british firm and the x-pipe looks like a much better fit than the standard cheap x-pipes on ebay.

just thought I would give everyone a heads up:

I saw that not too long ago. I was about to order one. Shipping alone is approx $41 to the US.

these will be nice in place of the 2nd cats.
