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.
