The Gibson dual cat-back exhaust for 2009–2014 Dodge Challenger R/T (5.7L) is a stainless system that produces a deep rumble and reduces backpressure to help acceleration and horsepower. Chambered Superflow mufflers tune flow using resonance chambers for aggressive sound with minimal interior drone. Polished slash-cut tips, mandrel-bent tubing, factory-style hangers and included hardware simplify bolt-on installation; lifetime limited warranty provides long-term coverage.
