The Gibson dual cat-back exhaust for 2011–2015 Dodge Challenger SXT (3.6L) is a stainless steel system tuned for a deep, powerful exhaust tone and reduced backpressure for improved acceleration. Chambered mufflers use resonance and louvered ports to shape sound while minimizing interior drone. Mandrel-bent tubing, polished slash-cut tips and factory-style hangers make this a straightforward bolt-on upgrade, and the system is covered by a lifetime limited warranty.
