Great Sound, smooth flow, I definitely made the right choice in choosing Flowmaster mufflers.

I purchased a 2016 Mustang GT used which had magnaflow's competition series on it. I had a shop retrofit the street series 12229 mufflers on and the sound is much better for daily driving. No drone at 2k RPM like with the competition series - it was really bad. I highly recommend the street series over the competition series.
