Just installed flowmaster outlaws and I love them loud, aggressive, and just down right mean. But the drone at highway speeds is horrible. Do you think dynomat or a dynomat like product would help? I know the trunk area has little to none as far a sound deadening.
Find specs on trunk space or use a tape measure to measure trunk floor and back trunk wall(backside of seats) you may need to do the under side of the rear seats and rear floor board if doing the trunk is not enough.
