I've tested the gas mileage difference between having this addition and not having it and still haven't came to a good conclusion. It seems like I've added a few MPG, but nothing too crazy. The sound is good and it was easy to install. I'll know more once I tune the vehicle. I'm very happy with it. Thanks for reading.
