Looking for advice on exhaust system.

On my 10 mustang V6 I used the Pypes cat back system with the violator mufflers and it had a hell of a bad drone 1800 to 3000

Yikes! Violator mufflers with any v6 is going to yield some pretty bad drone. Not something I would recommend. Sorry you had to deal with that. :(

Even on a V8, the Violator is not for the shy. ;)
