Replace your 2015-2017 V6 or 2.3L Ecoboost Mustang’s tame stock exhaust with our LoudMouth LM-1 kit and get a more aggressive sound and less backpressure while cutting weight as well. The LM-1 kit uses mandrel bent stainless steel 2.5-inch tubing with a minimum amount of turns or bends, creating a much less restrictive system. Custom 304 stainless steel tips are tailored to the Mustang’s rear fascia. LoudMouth kits utilize the factory mounts and come with pre-welded hangers for a painless and fast install. Against the stock 2015 Mustang exhaust, the LoudMouth LM-1 kit is 29 lbs. lighter and is 50 state emissions legal.

As a straight through system, there is no sound deadening material or resonators in this kit. Check your local noise ordinance laws for legality.
