MBRP S6204AL 4 Inch Turbo-Back Exhaust System Aluminized Steel Single Side Exit

The MBRP S6204AL is a complete 4-inch turbo-back exhaust system designed for 1999-2003 Ford Excursion models with the 7.3L Power Stroke diesel engine. Part of MBRP's Armor Lite Series, this system delivers professional-grade fitment, performance gains, and aggressive exhaust tone at an accessible price point.

Construction and Design:

Built from heavy-gauge aluminized steel tubing, this exhaust system offers excellent durability and resistance to road debris damage. All tubing is mandrel-bent to maintain consistent inner diameter through every bend, eliminating flow-restricting ripples and maximizing exhaust velocity. The single side exit configuration includes a mirror-polished 5-inch outer diameter tip for a finished appearance.

Key Features:

• 4-inch mandrel-bent aluminized steel construction throughout
• Turbo-back design replaces restrictive factory exhaust from turbo outlet to tailpipe
• Single side exit configuration with polished tip
• Bolt-on installation with vehicle-specific fitment
• Enhanced exhaust flow improves turbo spool and engine efficiency
• Deeper, more aggressive exhaust note compared to stock
• 5-inch OD mirror-polished stainless tip included

Performance Benefits:

By eliminating exhaust restrictions, this system allows the 7.3L Power Stroke to breathe more efficiently, reducing backpressure and exhaust gas temperatures. The result is improved throttle response, better turbo performance, and potential gains in horsepower and fuel economy. The aluminized steel material makes this an ideal choice for vehicles in dry climates or enthusiasts seeking performance on a budget.

Important Notes:

This exhaust system is designed for off-road or racing use and is not intended for vehicles equipped with catalytic converters. Installation requires removal of factory emission components. Verify local regulations before installation.

What's Included:

Complete turbo-back exhaust system with all necessary pipes, clamps, hangers, and hardware for bolt-on installation. Mirror-polished stainless steel tip included.
