Construction & Design

The Gibson Dual Split Cat-Back Exhaust is crafted from premium stainless steel, ensuring excellent resistance to rust and corrosion even in harsh environments. The mandrel-bent tubing maintains a smooth, consistent diameter through all bends, preventing flow restrictions and preserving exhaust velocity for maximum power gains.

The Superflow™ muffler features a baffled and chambered design without internal packing, which minimizes the risk of muffler degradation over time and significantly reduces interior drone for a comfortable driving experience. Polished stainless steel slash-cut tips provide a clean, aggressive exhaust exit that enhances the Dodge Ram’s rugged appearance while maintaining factory-style fitment.
