The American Thunder system is for the person who is looking for a complete Crossmember-Back dual exhaust system with a deep powerful sound. The system is constructed from 2.50-inch mandrel-bent stainless steel tubing and includes an H-pipe to balance the exhaust pulses and to eliminate back-rap on deceleration. The large cased Super 40 Series performance mufflers generally deliver a moderate interior tone with a deep powerful exterior sound which is suited for enthusiasts who want their performance to be heard. The mandrel-bent tailpipes exit straight out the back under the rear bumper for a strong muscular appearance and allows you to select your own style of tips. Designed for an easy fit, these systems include all necessary parts and hardware for easy installation and is covered by our Lifetime Limited Warranty. .
