Just got some cool mods for the ride, check this out:

Silverline T-304 4" turbo back exhaust system

Aeroturbine

TAG

Got them all from Dave at http://www.dieselperformanceparts.com

Completely changed the character of my truck, smooth take off, pulls like crazy, I swear it sounds like a big block V8 growl in the cab at speed, but not loud or the drone sound. I had put the AFE Stage II system in a while ago, but I never could hear the turbo whistle, now I can, sounds great Well my old system was factory and sounded more like tin cans put together. Anyway everything was installed in under 1 hour. Super well designed systems, worth every penny, and it's also beautiful. Give Dave a call today. eg
