Seguler 5" Dp-Back pipe & CCV Reroute EGR cooler Delete Kit for 2011-2022 6.7L Powerstroke
Product Overview
Key Features
Q: Why combine a 5" exhaust, EGR delete, and CCV reroute in one kit instead of upgrading individually?
A: Each component targets a different point in the 6.7L’s airflow chain. The 5" exhaust opens the exit path, the EGR delete shuts down soot entry into the intake, and the CCV reroute blocks oil vapor from fouling the turbo compressor. Upgrading all three together ensures no single contamination source or restriction point is left behind to limit the benefits of the others. It also consolidates the installation labor at the shared access points.
Q: How does the EGR delete help preserve engine health on the 6.7L?
A: The factory EGR system routes exhaust gas — which contains abrasive carbon particulates — back through the intake manifold. Over thousands of miles, this soot accumulates on intake surfaces, swirl valves, and valve stems. By bypassing the EGR coolers, this kit stops the continuous cycle of soot ingestion, helping to maintain cleaner intake airflow and reduce the long-term wear associated with carbon-laden combustion charge air.
Q: Where does the crankcase blow-by gas go after the CCV reroute is installed?
A: The CCV reroute kit redirects crankcase pressure and oil mist through a dedicated hose that vents safely toward the undercarriage, away from the turbocharger inlet. This prevents oil from pooling in intercooler pipes and coating the compressor wheel, while still allowing the crankcase to breathe properly.
Q: How does the 5" exhaust compare to a 4" system for daily driving and towing on the 6.7L?
A: The 5-inch system provides maximum flow capacity, the deepest available exhaust note, and the greatest EGT reduction under sustained heavy load — ideal for high-output builds and owners who want the largest exhaust upgrade. A 4-inch system delivers a more balanced profile focused on everyday drivability and towing comfort with less cabin presence.
