MagnaFlow 1984-1987 Buick Regal 3.8L Street Series Cat-Back 性能排氣系統 16884

The sound is exactly what I wanted—deep and aggressive without being obnoxious on the highway. The perforated core really opens it up when I get on the throttle, and the tone stays clean even at cruising speeds.

The install was straightforward on my '86 Regal, and that deep, resonant tone at startup is exactly what I was hoping for. Even better, I can actually feel a difference in throttle response compared to the old rusted system. It's exactly the sound this Buick needed.

Installation was straightforward, and the sound is just deep enough without being obnoxious on the highway. I do wish the tip sat a little more flush with the bumper, but the dyno-proven performance boost is noticeable.
