817739
The Flowmaster American Thunder® Exhaust System is engineered for the vehicle, providing aggressive exterior sound while maintaining moderate interior tone and all the performance benefits expected from Flowmaster®. Mandrel-bent dual 3.00-inch stainless steel tubing flows through the exclusive Scavenger Series® X-pipe for maximum power and deep, unique tone.Exhaust then passes through Super 40® Series mufflers, and the tailpipes feature “dummy valve stands” to allow factory actuators to function without triggering error codes, giving wide-open sound and performance at all times. The quad 3.50-inch polished 304 stainless steel tips exit cleanly within the rear valence for a muscular look.Constructed entirely from 409S stainless steel, this bolt-on system uses all factory hanger locations for a simple installation. Includes all necessary hardware and instructions, backed by Flowmaster’s Lifetime Limited Warranty.
