Introduction

The 5-inch Powerstroke downpipe-back race exhaust is a full CAT and DPF delete system for the 6.7L Powerstroke, built for off-road and competition trucks that need maximum flow and hard throttle response.

Vehicle Compatibility

• Years: 2011–2022
• Make: Ford
• Model: F-250, F-350, F-450 Super Duty
• Engine: 6.7L Powerstroke Diesel
• Body: Pickup (Does not fit Cab & Chassis)

Please Note: 2017+ trucks with the optional 5th wheel hitch prep package require exhaust modifications for over-axle pipe clearance

What's Included

• 5" Downpipe-Back Exhaust System – full DP-back delete pipe, no muffler, downpipe exit to tailpipe
• OE-Style Hangers & Hardware – all mounting hardware and factory-style hangers included
• Material Choice – customer choice of T304 or T409 stainless steel

Technical Specifications

Key Features & Build Details

• 5" Stainless Steel Piping – full 5-inch diameter from downpipe to tip. Eliminates the factory flow restriction and supports higher exhaust volume under boost.
• T304 or T409 Stainless Steel – T409 handles heat well for most builds. T304 adds more corrosion resistance for high-salt or wet environments.
• No Muffler, No Bungs – straight-through competition pipe. No flow restrictions, no bung ports.
• OE-Style Hangers & Full Hardware – bolts in using factory hanger locations. No fabrication needed on standard fitment trucks.

Performance Benefits

• Maximum Exhaust Flow – removing the CAT and DPF eliminates the two biggest exhaust restrictions on the 6.7L. Supports better scavenging and more airflow through the turbo.
• Lower EGTs – unrestricted flow moves heat out faster. Keeps EGTs in check under hard pulls and heavy loads.
• Sharper Throttle Response – less backpressure means the turbo spools faster. Boost builds quicker and throttle response tightens up.

Installation Notes

Bolt-on install using factory hanger locations. All hardware included. Race tuning required before running this exhaust. 2017+ trucks with the optional 5th wheel hitch prep package will need the over-axle section modified for clearance. Does not fit Cab & Chassis. Off-road and competition use only.

Frequently Asked Questions

Q: What is the difference between T304 and T409?
A: T409 handles exhaust heat well and works for most builds. T304 has higher chromium and nickel content, making it a more premium choice for wet or high-salt environments.

Q: Will this fit a 2017+ truck with the 5th wheel hitch prep package?
A: Not without modification. The over-axle pipe section will need to be modified to clear the hitch hardware.

Q: Are there bungs for O2 sensors or EGT probes?
A: No. This is a no-bung competition pipe. Any sensor ports needed will have to be added at install.

Q: Is race tuning required?
A: Yes. Race tuning is required for optimal performance.

Q: Does this fit Cab & Chassis models?
A: No. Not compatible with Cab & Chassis configurations.
