"Overall this piece is great. install was easy but the instructions were a bit vague. Also if you have lited your truck as I have you will need to slightly change the fit of the exit pipes and the way the muffler sits. But it i a great sound and still looks good."

"Great product! Big improvement on the stock system. Worth the money. I had a little trouble getting the dual exhaust level but that was purely a cosmetic issue. The clamp are little tough to tighten down but with an extension on the ratchet it tightens much easier."

"Bought it to add some sound to my truck. Sounds great, and improves efficiency. Easy to install using general everyday tools. Highly recommended if you want to add some quality sound, improve exhaust flow, but not "break the bank"!!! -Eric Baltimore, MD"
