When you're outside while it's idleing it sounds like an 18 wheeler!

It really sounds awesome.

I should have told them to have it ready tomorrow night instead of Wed.

 

I like the sound of the stock exhaust. It's quiet but the authorative sound of the Cummins is there in capital letters... When you get the chance, drive slowly by a concrete wall on the right side with the right rear window down and gently accelerate. Mark Martin's sponsor ain't got nothin on the sound of our Cummins exhaust!
