Looks like a decent setup. I went with a Dynomax system on my Silverado and I wanted the stock style single exit pipe on the side because I didn't want any chance of exhaust getting all over the boat while towing it around. Getting the stock exhaust out was fun as the ball and socket joint clamp had completely rusted the nut and bolt. That was an hour's worth of fun with a hack saw. I got the stock exhaust out without damaging it so it can be reused. The Dynomax setup was for an extended cab or longbed so I had to cut back part of the intermediate pipe. But it all went together really fast and fit in the stock location really well. I didn't put the 4" stainless tip on because I don't like it and I think it might hit the body. It has one of their VFT mufflers which has a spring loaded valve inside that forces the exhaust through the muffler at low speeds and is very mellow/quiet, but at high speeds it opens and is a straight through muffler. It seems anything is better than a stock setup on a truck!
