Product Description

The Gibson 619687 cat-back exhaust is Gibson's most popular system for the Ford Explorer and Mercury Mountaineer, designed for reliable performance and a straightforward, factory-style rear exit. Its Superflow muffler uses a baffled and chambered internal design rather than packing material, delivering an aggressive exterior tone while keeping interior drone to a minimum on long drives.

Built from stainless steel mandrel-bent tubing and finished with a polished T-304 stainless steel slash-cut tip, this system installs as a straightforward bolt-on using factory-style hangers and clamps - no welding or cutting required. With average gains around 5-10 hp, it's a reliable upgrade for Explorer and Mountaineer owners wanting more usable power alongside a genuinely aggressive sound - just confirm your vehicle isn't equipped with rear self-leveling suspension, as this system isn't compatible with that configuration.
