I searched and read reviews all over the net, studied for 3 months. This is the best deal I could find. Pipe is pipe and you must be careful to not be paying for a "name". This system was installed by me in about 1 hour, with some adjustments. All parts fit together like a glove, exactly as described with all stock hangers alligned without a fight. Instructions were easy enough although I didn't really need them. They included a muffler delete pipe that was a big free bonus but I chose to use the muffler. The system has a great low rumble tone with the muffler. Yes, I did gain about 1.5 MPG on testing so far. Yes, the throttle response is considerably better with no turbo lag. Truck feels like it gained 50 HP but I know that's not correct. Fit and finish is great with the included polished tip. Overall great stainless steel system with bonus parts that sounds, looks and performs great. Well worth the money. Not sure how they are selling this at such a low cost but I'm glad I found it.
