When we got our new car, I noticed a vibration and shake @ 1800-1900 rpm. I called the dealer and he said it was an exhaust drone and was normal. As you know the exhaust is the most restrictive i've ever seen so to satisfy my curiosity i had the local muffler shop cut off the "silencer" aka #2 muffler and put in a free flowing 3" after market exhaust tip. The drone is gone and the car seems to feel a little less restricted. The sound is suprising too! It's still quiet on the inside but when you are behind it you can hear that dodge v8 grumble.

 

Was this the Hemi? Or 4.7 V8??

 

It's the 4.7. It's been about 1500 miles since the modification and the exhaust seems to have gotten louder
the best part is, my wife really likes the sound too. I took the "silencer" to the shop and the welded it on my subaru aka p.o.s. and now it sounds like a rice rocket. win, win I guess.
