MagnaFlow 2011-2015 凱迪拉克 CTS 6.2L Street Series 觸媒後段性能排氣系統 15496

I've had this exhaust on my CTS for a month now and the sound is just right—loud enough to feel aggressive but no drone on the highway. The dyno-proven performance gain was noticeable, especially when merging onto the freeway.

The deep, resonant tone at startup was exactly what I wanted for my CTS, and it's remarkably civil on the highway. Even at partial throttle, the dyno-proven performance is clearly noticeable. No annoying drone at cruising speeds, just a solid, purposeful sound.

The dyno-proven performance claim caught my eye, and after a few weeks with this system, I can feel the difference in throttle response. The tone is deep and refined at cruising speeds, then opens up nicely when I step on it.
