With the 4" delete pipe turbo back to the stock factory mini muffler & stock tailpipe, I'm not getting any noticeable drone towing or empty. It just sounds like a diesel should.

I really haven't had anyone else drive it since my deletes so I could hear it going up the road or coming back with the EB on to get a feel what others are hearing as far as the outdoor exhaust noise level goes.
