7 Another great way to save weight and increase power to the wheels is by installing an aftermarket exhaust to replace the factory stuff which is heavy and restrictive. Razor's Edge Motorsports has exhaust systems in stock that will shave weight from your Mopar in addition to letting your Hemi breathe a little easier. We already have track times for our Challenger in stock trim and since the ProCharger and rollbar installation. Be sure to watch future issues of Mopar Muscle as well as Mopar Now, as we further lighten our late-model Challenger with a Razor's Edge K-member, and then take our car to the track to see the results.
