MagnaFlow 2002-2006 Cadillac Escalade 6.0L / 2002-2006 GMC Yukon Denali 6.0L Street Series Cat-Back Performance Exhaust System 15734

Installed this on my Denali last weekend and the sound at idle is deep without being obnoxious. Really woke up the 6.0L, especially when you get on it.

I’ve had this exhaust on my Yukon for three weeks now, and that deep, mellow rumble at idle is exactly what I was hoping for—much more aggressive than stock. The improvement in low-end torque is noticeable, especially when merging onto the highway.

Honestly, I bought this mainly for the sound, and the 6.0L really growls through the cat-back at highway speeds, even if it's not crazy loud inside. Drone is minimal and I actually noticed the throttle response feels a bit more eager around town, which is a nice bonus.
