Love it ease of installation 2.5 miles per gallon on a recent highway trip and noticeable pep off the line!!!

First off, the sound is amazing, not too loud, but powerful. I haven't drove enough to check mileage, but assume it will increase a bit. Could immediately tell the increase in HP. I would definately recommend.
