I bought my 01 2500 a couple years ago and while on the test drive my buddy pulls the silencer ring out of the glove box. It looked like it wasn't in for very long before it was taken out. I put it back in about 2 months ago and haven't been able to tell the differece. It is very noticeable when I pull a hill. Does having a k&n air filter and full affrighted pipe 4" exhaust have somethin. g to do with the turbo being so loud?
