Exhaust Dampener
I read somewhere that GM installed some sort of "flap" 
in the exhaust system on late model C4s to lower the tone at low speeds. It supposedly opens when throttle is given. Has anyone found and removed this device?

ericcer put together a very tidy exhaust arrangement. I had some
suggestions about the oil accumulator, but the exhaust is
exceptionally nice, IMO.

No such animal on factory LTx systems. But it's always great to hear a new urban legend. Pass it on....
