Rather than spending $500+ on exhaust for our 2004 durango with the hemi I ordered a 3" Summit Racing glass pack and took it out the back with 3" exhaust pipe. It sounds great and it turns heads when you really get on it. It does not resonate bad at all and is quite enough for those long trips. The wife and the kids do not complain at all. Everything all together was about $150. It has more power and you can hear what the transmission is doing. Next I need to get a cold air intake. If you do not want to spend the money on brand name exhaust try this setup, I think you will be very happy. Sounds awsome
