The system is sweet. I am averaging between 1 and 2 mpg better than the stock system and the tunes are sweet as expected. 1 issue was the components package in the box with all the clamps and brackets was torn open and the special clamp for the catalytic converter connection was missing, fortunately I was able to reuse the old clamp. That is a special clamp and would have been an issue if the old clamp was unusable.

I installed the Borla Cat Back Exhaust with duel pipes out the rear of the truck. The truck looks and sounds great. Installation was not too bad. Most of the effort was with taking off the stock exhaust. Had to make two cuts between muffler and catalytic converter and one after the exhaust. Once it was out, the new system installed easily. Only advice I can give is to make sure your blade is shape when cutting out the old system and invest in a torque wrench so the installation of the new system is to spec. Regarding gas mileage, I also have a K&N Cold Air Intake and am getting about 21.5 miles per gallon during a highway trip (cruise set to about 74 mph). Normal daily driving to and from work I'm averaging 18-19 mpg. My next purchase with be a programmer for the truck computer....then I'll be done. The truck also sounds great. Low rumble. Quiet during highway / normal driving and growls nicely if you jump on it. I struggled regarding with option to purchase (dual out the back or out the side). Glad I went with out the back. Looks outstanding. Good luck with your project. Very happy with the Borla Exhaust.

Love this exhaust, really happy I did the research and that I went with Auto Anything, the best price and they will beat the price of anyone (it will be less). Gas is not improving because I cant keep my foot out of the accelerator. My fault but it just sounds so good, bought the touring one, just right, nice at start up and when you get in it, but almost factory at highway speeds, no annoying drone noise. Once you get the factory one off (follow the directions load up the rubber hangers with W-D 40 and will make your life easier) the new one really goes right on. Maybe 45 minutes with two guys taking there time to line everything up (dual exhaust coming out the back). Hardest part was the clamp that holds the pipe to the catalitic convertor.

The system arrived promptly. The box was already open but all parts were included. I had a local shop do the install and the engine side muffler bolt-on flange was too big. Directions state to re-use the factory clamp. When completely tightened there was still play in the connection. Rather than try and get everything back in the box and pay to have the factory system re-installed, I had him weld and clamp the connection. Other than that, the system looks and sound good. It's not too loud on my '11 Silverado and that's just what I wanted.

Received exhaust kit and installed easily, however, there were no directions shipped with the kit. Specify where and how to mount the additional hanger and the heat reflective tape that came with the kit instead of assuming where and how to put them in. Sounds great.
