Cranking up the aggression of your Mustang's exhaust note while winning an extra jolt of rear wheel horsepower and torque into the bargain is as easy as installing 2015 Mustang down pipes in your brand-new Pony. These downpipes, produced by several different high quality aftermarket part manufacturers, usually come with integrated high-flow catalytic converters. These meet legal strictures while boosting exhaust flow for a notable jump in power. Feeding extra horsepower and torque to the rear wheels of your 'Stang gives it powerful acceleration and the ability to show off its muscle right from the starting line or the stoplight. Mandrel-bent construction is generally standard in these cutting edge exhaust fixtures to make sure the gasses flow freely and strongly through the whole system.
