Flowmaster's race-oriented Outlaw® Extreme Cat-back system is designed for the enthusiast looking for the maximum sound level and performance from their 1986-2004 Mustang GT, LX and Cobra models with either a 4.6L or 5.0L engine. The turn-down tailpipes drop at the rear of the transmission and eliminates full length tailpipes to maximize the sound level and allow for extra clearance for wide tires and modified suspensions. This mandrel-bent system is designed to mount behind the factory catalytic converters, or most factory style aftermarket H-pipes. The Outlaw Extreme system delivers a super aggressive interior and exterior tone and is suited to the enthusiast who wants the most aggressive components they can purchase. Like all Flowmaster® systems, the benefits include improved throttle response and power. Designed for an easy fit, these systems include all necessary parts and hardware for easy installation. Note: Ideal for off-road racing use.
