FITMENT
- 2011-2023 6.7L Ford Powerstroke F-250 F-350 F-450 Super Duty V8 Diesel.
- Not fits Cab & Chassis trucks.
DESCRIPTION
Product Overview
- Bottlenecked exhaust paths and trapped thermal energy are major weak points for factory 6.7L Ford Powerstroke diesels. The stock catalytic converter and DPF generate heavy backpressure, triggering frequent regen cycles and trapping extreme heat under heavy loads, while the factory EGR routes abrasive exhaust soot back into the intake manifold.
- Engineered as a total breathing overhaul, this 6.7L kit combines a high-velocity 4-inch mandrel-bent exhaust line with a dedicated EGR cooler bypass assembly. It drastically cuts exhaust backpressure, stops soot contamination in the intake tract, and keeps your engine running cooler for sustained towing performance.
Key Features
- Precision mandrel-bent 4-inch exhaust tubing preserves high exhaust gas velocity for snappy variable-geometry turbo response
- Fully bypasses the factory EGR cooler, stopping carbon sludge accumulation and neutralizing coolant leak failure risks
- Removes the flow-choking DPF and catalyst brick, ending fuel-wasting regen cycles and lowering EGTs during heavy towing
- Comprehensive airflow overhaul targeting both the intake contamination pathway and the exhaust restriction in a single job
FAQ
Q: Why upgrade the exhaust system on a 6.7L Powerstroke?
A: The factory exhaust is designed around emissions compliance, which introduces significant flow restriction as exhaust gases force through dense DPF media and catalyst substrates. Replacing these with straight-through 4-inch tubing eliminates that bottleneck, dropping backpressure and lowering EGTs for faster turbo spool.
Q: What specific problems does this combination kit solve?
A: It addresses restricted exhaust flow from the factory DPF and catalyst system, plus EGR-related carbon soot accumulation throughout the intake tract. By opening the exhaust exit while sealing off soot recirculation, the kit improves both sides of the combustion cycle in one coordinated installation.
Q: Why address the exhaust and EGR systems together rather than separately?
A: Exhaust restriction and EGR contamination affect different sides of the engine but share overlapping labor access. The exhaust side improves outflow while the EGR delete cuts intake contamination, making one coordinated install more efficient.
Q: Will this kit help keep the intake tract cleaner over the long term?
A: Yes—bypassing the factory EGR system significantly reduces the volume of exhaust soot recirculated into the intake manifold, minimizing carbon deposits on intake valves, runners, and port surfaces. Keeping the intake clean preserves airflow velocity and prevents the progressive power loss carbon buildup causes.
