Sounds the way a Hemi should! Not the best welds.
I absolutely love how this dounds with mid muffler delete replaced with an X-Pipe. Deep growl like an old school Hemi. Tips were welded crooked. So it doesn't sit properly had to angle mine down to avoid hitting. One side is straight other side off to the left. Will try bar clamping with a torch to fix issue. Other then that issue it was the sound I wanted and was not disappointed with that!
If u have a gen 3 Durango they are difficult to put in because there's no room to put the bolts on the headers themselves. I recommend o2 sensor extension which kooks doesn't supply they give u only two long extension. On the durangos you need four in order to connect the o2 sensors. I definitely recommend these just make sure you set aside at least 8 hours to put them on.
