This SLP Performance Parts Axle-Back kit eliminates the restrictive stock mufflers from the 2011-2014 GT or GT500, drastically reducing back pressure to enhance power and to produce one of the most aggressive exhaust notes possible with the factory catalytic converters still installed.

SLP's Loud Mouth axle-back system is made from 2.5" mandrel-bent 409 stainless steel tubing, which has excellent flow characteristics and features pre-welded hangers for simple installation. The hand polished, 4" dual wall tips give a show quality muscle car appearance to the rear of your Pony.
