MBRP S6216409 4" XP Series (Armor Plus) Turbo-Back Exhaust – 2003-2005 Ford Excursion 6.0L Power Stroke

Upgrade your 6.0L Power Stroke with the MBRP S6216409 4-inch XP Series turbo-back exhaust system. Built from durable T409 stainless steel, this system is designed to free up exhaust flow, reduce backpressure, and deliver a deeper, more aggressive exhaust note while maintaining everyday drivability.

Key Features

• 4" Mandrel-Bent Tubing – Smooth, consistent diameter throughout for maximum exhaust flow and reduced restriction
• T409 Stainless Steel Construction – Excellent corrosion resistance for long-term durability in harsh conditions
• Single Side Exit – Clean look with a polished 5" OD T304 stainless steel tip
• Stock Catalytic Converter Compatible – Designed to retain the factory catalytic converter
• Bolt-On Installation – Uses factory hanger locations with all necessary hardware included
• Street-Friendly Sound – Aggressive tone without being excessively loud
• Lifetime Warranty – Backed by MBRP’s industry-leading lifetime warranty on the system

This turbo-back system replaces the restrictive factory exhaust from the turbo outlet back, helping your 6.0 Power Stroke breathe easier for improved throttle response and efficiency. The heavy-duty T409 stainless construction stands up to road salt, moisture, and high exhaust temperatures better than aluminized systems.

Fitment: 2003–2005 Ford Excursion 6.0L Power Stroke only.

Perfect for Excursion owners looking for a durable, high-flow exhaust upgrade that balances performance, sound, and longevity.
