    Description

    Loud Aggressive Sound. Add Borla excellence to your coyote powered GT Mustang with a Borla 3" Cat-Back exhaust. This Borla Cat-Back will greatly improve your 5.0's exhaust flow for more power and an aggressive muscle car sound that everyone will love.

    Street or Off-road Use. The Borla Cat-Back Exhaust X-Pipe bolts up directly behind the stock catalytic converters making your Mustang 100% smog-legal. Or it can be installed with Borla's XR-1 Long Tube Headers, deleting the stock cats for even more power and making it perfect for off-road use.

    High Quality Construction. Constructed from ultra smooth mandrel bent 3" stainless steel tubing to improve exhaust flow, the Borla Cat-Back Exhaust System includes an X-Pipe and features two race inspired mufflers with 4.5 inch polished stainless steel slant tips for aggressive sound and impressive looks.

    Application. This Borla 3" Cat-Back Exhaust System with included X-Pipe has a versatile design that allows it to fit 2011-2014 GT and 2011-2012 GT500 Mustangs equipped with either the stock manifolds or aftermarket shorty headers installed. It can also be installed on 2011-2014 GT or 2011-2012 GT500 Mustangs with a set of Borlas XR-1 Long Tube Headers by deleting the catalytic converters.

    Technical notes. By removing the catalytic converters this exhaust is no longer legal for use on pollution controlled motor vehicles; and will be intended for off road use only.
