My ears are bleeding.... I love it. For real though, it's a little louder in the cab than I wanted, but I'm glad I didn't go with the Super 10. Good price, gotta love AutoAnything. Had it welded, only way you should do it really, and appearance I could care less about because no one is going to be looker underneath my truck.
