Two weeks ago ... installed GMC performance exhaust.

Last week ... installed Range DFM disabler (RA007).

Pretty happy with both. Exhaust doesn't center on the cutout in the rear, and stealership can't do anything. So I am going to take it by an exhaust shop tomorrow to see if they can adjust. Pretty annoyed by that.

Can you share some more about the DFM Disabler? I didn't realize they were available for our trucks.

Also, do you know if it conflicts with the Autostop Eliminator? I've got that installed already.
