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.
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.
