The MBRP S6212P is a 4-inch aluminized turbo-back exhaust for 2003-2007 Ford F-250 and F-350 Super Duty trucks with the 6.0L Power Stroke. This system includes a 3.5-inch downpipe that steps up to 4-inch tubing after the catalytic converter, and re-incorporates the factory catalytic converter.
The factory catalytic converter must remain in place. This system cannot ship to a California or Colorado delivery address.
- Your 2003-2007 F-250/F-350 has the 6.0L Power Stroke.

- A 1-year warranty fits your budget.
- Your truck is a Regular Cab without the separate adapter (MBRP FS9449).
- Your truck is an F-350/450/550 Cab & Chassis.
- You plan to keep the truck long-term and want a longer warranty - see S6212AL 4-inch aluminized turbo-back exhaust.
- Confirm your cab type - Regular Cab trucks require the separate adapter (MBRP FS9449).

- Confirm your ship-to address is outside California and Colorado.

Built by MBRP
MBRP mandrel-bends the downpipe and tailpipe with minimal bend-degree angles, which cuts backpressure and helps the 6.0L breathe. The 3.5-inch downpipe joins the 4-inch tailpipe just ahead of the transmission cross member, a routing choice that avoids removing the cross member during installation. Every seam is fully sealed to guard against rust-through, and this platform has shown gains of up to 18 hp and 28 lb-ft of torque in MBRP's testing.
MBRP publishes the official S6212P installation instructions (PDF) for this system, covering removal of the factory exhaust and step-by-step installation.
Fitment Checks That Matter
- Catalytic Converter: The factory catalytic converter must remain in place.
- Cab & Chassis: This system is not designed for F-350/450/550 Cab & Chassis trucks.
- Regular Cab: Regular Cab trucks require the separate adapter (MBRP FS9449).

Avoid These Common Mistakes
- Ordering for a Regular Cab truck without the adapter. Regular Cab installations require the separate adapter (MBRP FS9449).
- Assuming the catalytic converter is included. This system does not include or replace the catalytic converter - it retains your factory cat.
- Ordering for a Cab & Chassis truck. This system fits F-250/F-350 pickups only.
If these checks match, the S6212P is the right MBRP system to order for a 2003-2007 Ford F-250/F-350 6.0L Power Stroke when you want the entry-level turbo-back with the factory cat retained.
