So as it says in the title I had my de$&@e done a couple of years ago.

If I believe the sound meter I downloaded ( which had a good rating from a magazine) I'm approaching 100db when climbing a hill. I recently straight piped the DPF filter in an effort to get the sound out from under the cab. That went well
