Bring Out The Power Your Excursion Was Built For

This setup delivers the kind of raw diesel tone and throttle response that makes your SUV feel more alive with every press of the pedal. Whether you're hauling a camper or just want more punch for your daily drive, this exhaust brings it all together, sound, performance, and presence. It keeps your factory catalytic converter in place, making it a practical upgrade for drivers who want more without giving up on emissions components. You’ll hear a deeper, cleaner exhaust note and feel smoother power through the midrange where it matters most. On top of that, it adds a sharp, aggressive edge to your Excursion’s personality without overwhelming the cabin. For diesel owners who want something that works hard and sounds great doing it, this system checks every box.

Engineered For Cooler Temps And Consistent Performance

The MBRP S6216409 system features a full turbo back layout, replacing everything from the turbo outlet to the tailpipe with high-flow 4-inch mandrel-bent T409 stainless steel tubing. This design significantly reduces restriction and backpressure, helping your 6.0L Powerstroke expel hot exhaust gases more efficiently, which in turn lowers exhaust gas temperatures under load. Retaining the factory catalytic converter, this system stays within compliance for many states while still providing measurable performance gains in horsepower and torque. T409 stainless steel construction adds solid corrosion resistance, especially in wet or snowy climates, while fully sealed connections help prevent rust-through at the joints. The single side exit maintains the stock routing, offering a clean, OEM-like finish that fits well with factory components. Installation is straightforward with included clamps and hardware, bolting directly to factory hangers without cutting or welding. It’s a reliable and well-balanced upgrade designed to deliver long-term benefits for everyday driving, towing, or weekend adventures.
