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.
Performance & Sound
By improving exhaust flow and reducing backpressure, this cat-back system typically delivers horsepower gains of 15 to 20 HP, along with increased torque. These improvements translate to better throttle response and enhanced towing capability. The exhaust note is deep and throaty, becoming more pronounced under load, such as during towing, without excessive cabin drone thanks to the muffler’s advanced design.

What does the Available to Promise date mean?
ETA stands for Estimated Time of Arrival. The date shown is calculated using our Available-to-Promise (ATP) system, which tracks real-time supplier commitments to determine when a product is expected to be available for delivery. Specifically, the date is calculated by adding 9 business days from the date a supplier has committed to ship the product, representing a worst-case scenario for when we can expect to receive inventory.
Please note: The ETA is an estimate, not a guarantee. While we work closely with our suppliers to keep dates as accurate as possible, delays due to shipping carriers, weather, customs, or supplier-side issues may occasionally push the actual arrival beyond the date shown. Likewise, inventory may arrive sooner than the ETA in many cases. If you would like to be notified for when this item arrives, sign up for our back in stock notifications!
