Used this on my 2002 Durango 4.7 - I had to modify it a bit (this muffler was shorter than my stock muffler and the hangers were welded to the stock muffler itself so that it had to be removed and welded back to the choke). Everything went well in the end, and the 4.7 now has a great sound: a nice hum that doesn't hum at high speeds. Very satisfied.
