Regardless..."Greg's" new stuff (as if I knew the guy personally) sounds really exciting. My ideal exhaust would be as quiet as possible (I dig the Z for its luxury as much as its performance), have the Labree bends (hence, theoretically, performance) and JRH(KY)'s quad oval appearance. If I could get all that for ~$800 shipped, I'd knock over the 7-ll (actually, it's a UDF...don't ask) in a heartbeat.
