Construction & Design

The Gibson Cat-Back Exhaust is crafted from high-quality 304 stainless steel, ensuring excellent resistance to rust and corrosion even under harsh environmental conditions. The mandrel-bent tubing maintains a consistent diameter through all bends, minimizing flow restrictions and maximizing exhaust scavenging for improved engine efficiency.

The Superflow™ muffler features a baffled and chambered design that expertly balances sound attenuation with a deep, aggressive tone. This design reduces unwanted interior drone, allowing for a more comfortable driving experience without sacrificing the signature exhaust character. Polished stainless steel slash-cut tips add a professional, factory-style finish that enhances the truck’s rear appearance while resisting wear and discoloration over time.

Factory-style hangers and mounting hardware ensure a secure fit and maintain proper alignment, preserving the truck’s original undercarriage look and function.
