Description
Overview
Flowmaster’s race-oriented American Thunder® Extreme Cat-back system is designed to mount behind the factory catalytic converters, or most OEM style aftermarket H-pipes. 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.These systems are mandrel bent for maximum performance and include Super 44 series mufflers. This American Thunder 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. Notes: Fits coupes and convertibles
