Seguler 4" Turbo Downpipe w/EGR delete kit for 2015-2019 Ford 6.7L Powerstroke

FITMENT

• 2015-2019 6.7L Ford Powerstroke F-250 F-350 F-450 Super Duty V8 Diesel.
• Not fits Cab & Chassis trucks.

DESCRIPTION

Product Overview

• Downstream restrictions and intake-side sludge are major performance hurdles on 6.7L Ford Powerstroke trucks. The cramped factory turbo downpipe creates immediate backpressure right at the turbine housing, while the OEM EGR and CCV circuits continuously feed sticky oil vapor and abrasive carbon soot back into the air inlet.
  
• Built to clear out these critical bottlenecks, this configurable 6.7L Upgrade Package combines a high-velocity 4" turbo downpipe with complete EGR Delete and CCV Reroute solutions. It maximizes exhaust scavenging directly off the turbo, prevents power-robbing intake deposits, and keeps your entire air-charge system running clean.
  

• Evacuate exhaust gases instantly with a smooth 4-inch mandrel-bent downpipe that reduces turbine-outlet restriction and lowers EGT under load
  
• Halt carbon sludge accumulation by permanently sealing the EGR circuit with precision CNC billet aluminum block-off plates and multi-layer high-temp silicone seals
  
• Separate crankcase oil mist inside the CCV housing using a multi-hole billet baffle plate that condenses vapor and returns oil to the engine — no external canister required
  
• Protect the turbo compressor wheel and intercooler boots from oil contamination that degrades boost efficiency and accelerates component wear
  
• Restore a clean, unrestricted airflow path through both the intake and exhaust tracts to support consistent engine efficiency across all driving conditions

FAQ

Q: Why package a downpipe, EGR delete, and CCV baffle upgrade together? 

A: Each component targets a different restriction in the engine’s airflow chain. The downpipe clears the exhaust side, the EGR delete keeps the intake side clean, and the CCV baffle stops oil vapor from fouling the turbo and intercooler. Addressing all three simultaneously delivers a complete airflow restoration rather than a partial fix.

Q: How does the CCV baffle plate function differently from a traditional catch can? 

A: Instead of collecting oil in an external reservoir that requires routine draining, the baffle plate installs directly inside the factory CCV housing. It uses a multi-hole condensing design to separate oil mist from crankcase vapor and drains the captured oil straight back into the engine, eliminating the maintenance burden of an external can.

Q: Can I combine this downpipe with a full cat-back or DP-back exhaust system? 

A: Yes — for maximum exhaust flow from the turbocharger to the tailpipe, pairing this 4" downpipe with a complete downstream exhaust system creates an uninterrupted high-flow path. This full-system approach delivers the most complete exhaust evacuation and EGT reduction possible on the 6.7L platform.

Q: Will the CNC block-off plates hold up under sustained towing heat? 

A: The billet aluminum plates and anodized fittings are engineered for the heat-soak conditions found in a hard-working 6.7L engine bay. Combined with multi-layer high-temp silicone hoses, they maintain a durable, leak-free seal even under extended heavy-load operation.
