I have had mine for 15,xxx + miles and the noise is not much more than the stock. I t changed my speedometer by about 7%. I tracked it on my GPS. The mileage will also change by the same 7% as it runs off your speedometer. I have the predator programer and adjusted my speed to within .25 miles per hour. Get them as soon as they are available. I run 46 P.S.I. and rotate and rebalance them every 3k miles.
