MagnaFlow 2005-2006 龐帝克 GTO 6.0L Street Series 觸媒後性能排氣系統 15892

The deep rumble at idle is exactly what I wanted, and the install lined up perfectly with the factory hangers. It's noticeably more responsive when I get on the throttle now.

The rumble at cold start is exactly what I wanted for the GTO, and the cat-back’s tone gets deeper as you get on it without any drone on the highway. It bolted right up to the factory hangers, so install was a couple hours in the driveway with basic tools.

The tone is exactly what I hoped for — that deep, resonant growl at idle, but it settles into a smooth cruise on the highway with zero drone. Fitment on my GTO was solid, though the tips sit slightly off-center if you're picky about that.
