Well to this point, after looking at everyone else's 09 come out, I decided just to go for broke and bought two flowmasters, part number 52580, 80 Series T/A mufflers. Same inlet size as the R/T exhaust. After looking at the underside of an 08 in person, It looks like it will be tight, but I will find a way to get them under there, maybe lift the back a bit or route them somewhere else.
