SLP Loudmouth Axle-Back Exhaust (11-14 GT & GT500)

Aggressive Throaty Exhaust Note. This SLP Performance Parts Axle-Back kit eliminates the restrictive stock factory 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.

409 Stainless Steel. SLP's Loud Mouth axle-back system is made from 3" 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.

Application. Made as a direct bolt on, this SLP Loudmouth Axle-Back bolts right up in the stock location without any modifications required on the 2011-2014 GT or GT500 Mustangs.

Technical note: AmericanMuscle recommends adding the 2005+ Mustang 304 Stainless Steel Exhaust Hanger Kit from the drop down option above, to provide more strength, stability and a cleaner installed appearance. If you have a 2007 Mustang you may need the kit for correct installation. Click here for details.
