wolfheads Member Jul 17, 2018 39 1 18 Florida May 23, 2019 #1 May 23, 2019 #1 I have a 1994 Mustang GT convertible that has 12" Borla mufflers and the drone is terrible at highway speeds. What can I do to tone it down? Change to different mufflers? Or install resonators? If so, what size and brand? Thanks guys.
