Test drove it and the first thing I noticed was the elimination of that truck-like sound in first gear at higher rpms. The sound we all know and auto journalist complain about when reviewing the car. The cab is significantly quieter and the mechanical noise has moved from the engine to the rear rear of the cockpit and specifically exhaust note.
This worked great on my car. I also think I gained an additional 8 horsepower at 5250RPMs.
Cheers.
