Changed out my 20 yr old glass packs for a set of Thrush Turbo #17715 2.5". I can now think and hear my stereo or talk to the wife while driving. They do have a nice rumble to them while at idle, but are oh so quite at 2500 rpm. This will be the new chapter in the truck. And hey if I want it loud I just flip the switch on the cutouts and you will know Im coming down the street.
