JackS, the 280E donor is something to consider. You'll have to shorten the 280E system. The downpipe will likely be too much trouble to modify. The M102 has 2 pipes from the exhaust manifold vs the US 280CE with a single pipe with a big ugly cat bulge.

It might be possible to merge the downpipe from a US 190E and the 'catback' from a US 280CE. I don't know if TimeValve will help you with that.
