I just installed after market single into dual exhaust. It is made by FLO-PRO #62021. No pictures sorry i cant figure out how to load? It connected where the two factory pipes came together then ran single to the rear where it fed into a smaller muffler in the stock location then split into two pipes with twin tips!!! Looks really cool, Now sounds like a perfed up six or a weak eight cylinder. There is a slight growl at an idle but not loud at driving speed you can hardly hear the difference and you cannot hear it over the music at all, Have not had time to drive it much so power difference i cant comment on but im sure it will compliment my CAI and chip once ive picked out.Will post pictures one day if i can figure out how.
