Description
High Flow Exhaust. Borla engineers have designed this cat-back to deliver a significant increase in airflow over the restrictive stock exhaust system for a dramatic increase in power and sound.
Aggressive Sound. The aggressive sound of the Borla Axle-Back comes from their signature "S-Type" Stinger Mufflers. The Stinger Mufflers are manufactured from aircraft-quality T-304 stainless steel and feature a Straight-through baffled design to produce an aggressive muscle car sound.
Durable Borla Construction. The S-Type Cat-Back a.k.a "Stinger" system is made from mandrel-bent 2.5" aerospace-grade austenitic stainless steel, and features 4" brightly polished tips for a super-aggressive appearance. This system also features Borla's popular "S-Type" mufflers for an equally aggressive sound.
Application. Designed to be a direct bolt on, this Borla Stinger S-Type catback will bolt straight up to the factory Mid-Pipe without any extra modifications required on the 1999-2004 GT, 2001 Bullitt, and 2003-2004 Mach 1 Mustang to give your Pony a rich muscle car sound.
