Had to remove the ECM to get room to install but was fairly easy to do. My truck runs great now. Same mileage or better but more power for towing.

I love it! It makes my impala preform like I expect it to and more. I installed it the same day as a drop in K&N filter and my car sounds awesome. I deffinetly recommend this to anyone. It made my car fun to drive again. Not sure yet on any mpg +/- because I can't keep my foot off the pedal. I was worried about passing an emissions test but it passed no problem. Biy this, you won't regret it!

in my opinion it's one of the best things you can do to open up your performance in your vehicle once you've done the Exhaust upgrades and cold air intake you can see a big boost in performance I can even sure from now and all 5 gears
