Part 16514. I have this and it's great. I thought the Magnapack model that has the Aggressive sound would be too much. 16514 is perfect. I combined it with a Mopar CAI, Diablo Tuner, and with the Magnaflow system you will have over 400hp in the R/T. Also, I had original reproduction exhaust (1970) tips welded on and the rear looks mighty retro! Good Luck.
