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
What is the difference between T304 and T409?
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.
Will this fit a 2017+ truck with the 5th wheel hitch prep package?
Not without modification. The over-axle pipe section will need to be modified to clear the hitch hardware.
Are there bungs for O2 sensors or EGT probes?
No. This is a no-bung competition pipe. Any sensor ports needed will have to be added at install.
Is race tuning required?
Yes. Race tuning is required for optimal performance.
Does this fit Cab & Chassis models?
No. Not compatible with Cab & Chassis configurations.
Please Note: For off-road and competition use only. Race tuning is required. 2017+ trucks with the optional 5th wheel hitch prep package require exhaust modifications for over-axle pipe clearance. Not compatible with Cab & Chassis configurations.
