Flowmaster American Thunder Cat-back System - 2014 Silverado / Sierra 1500



This is a complete 409S Cat-back system for the newly redesigned 2014 Chevrolet and GMC 1500 series pickup trucks with the 5.3L V8 engine. It's designed to fit Double Cab and Crew Cab models with 5.5 or 6.5 bed. The system connects just behind the factory catalytic converter with a flanged inlet pipe and braided flex connector. The muffler in the system is a single inlet, single outlet Super 50 Series. The single 3.0" tailpipe exits out the side in the factory style, and includes a 3.5" dia, double wall polished 304S stainless tips. As an Force II system, it will generally provide a moderate sound level both inside and outside of the vehicle. The sound while in MDS mode is very tolerable and should not be an issue for the majority of customers. The system includes all the hardware necessary for a simple at home installation.
