Good fit, easy installation. I matched it with a banks automind tuner and volant cai, and in sport mode, my truck 2008 6.0l 1500 Sierra,feels like a race car. Torque and shift points were adjusted and the exhaust sounds good. I didn't want it too loud, and it is just right. A nice throaty rumble, but not obnoxious.
