Dodge Durango Forum II

Did they put on a regular 40 series or a Delta Flow 40 series? Both Delta Flows are a lot quieter...>>

I would have like the higher exterior sound level of the Delta Flow 40, but I DIDN'T want the higher interior level of it. No way in hades would I want a regular 40 series. They're getting in the abnoxious range for my tastes.

Plus the wife would have kicked me out if I had something that loud! :-)
