MagnaFlow 2015-2020 Chevrolet Tahoe 5.3L / 2015-2020 GMC Yukon 5.3L Street Series 觸媒後高性能排氣系統 15355

The deep, resonant tone when I start it up is exactly what I wanted, and I can actually feel a difference in throttle response. It gives the Yukon a much more aggressive personality without being obnoxiously loud on the highway.

Installation was straightforward and took me about an hour in the driveway. The exhaust note is deep and throaty at idle, but civilized on the highway. I can definitely feel the extra torque when merging onto the freeway.

I was worried the sound might be too aggressive, but the deep, resonant tone at cruising speed is surprisingly refined and actually turns heads. The dyno-proven performance difference is noticeable when merging onto the highway.
