I have a 2007 unlimited and I want exhaust but I don't want anything loud just a little hum, what would be the best cat back system for a daily driver. I just don't want anything obnoxious or to loud, any suggestions or info would be greatly appreciated

 

Dynomax VT

 

My vote is Dynomax Ultra flo. Offered in rock crawler style or evolution competition style. (both sound the same) It mellows a bit after its been installed for a while.

 

The duel exit Rugged Ridge muffler is the ticket for subtle but very good mello performance sound.
