I had the flow masters on my old truck with headers and a 340. In my opinion they sound awesome and got comments everywhere, they are crazy loud outside as well as inside the car. Driving on the Hiway was horrible. If I was putting mufflers on a car that was only used for short trips and screwing around I would maybe use them again however if you plan on driving a lot the drone will pound in your head. When I had them I got pulled over once because the police thought I had no mufflers. This comes down to personal preference on any make.
