Where did you get the new exhaust (for future reference)?
Yeah, I think it is possible that my coder (Pro-Series CAN OBDII Code Reader, http://www.diydiagnostics.com/ ) doesn't distinguish between past and current codes. It does distinguish between pending and current codes though.

I got the exhaust work done at Walt's Emissions (the shop on Aurora). I'm happy with their service.
