DESCRIPTION
Product Overvie
-
The 2013–2018 Dodge Ram 6.7L Cummins comes restricted from the factory by a massive emissions mid-section containing a DPF, catalytic converter, and SCR (DEF) system. These heavy components trap extreme thermal heat, trigger frequent fuel-wasting regens, and choke backpressure right behind your turbo.
- The 4" DPF & SCR Delete Race Pipe is the ultimate high-flow mid-section solution. Constructed from smooth, mandrel-bent 4" T409 SS, this straight race pipe replaces all restrictive mid-body emissions units. By opening up the exhaust pathway, it sharply drops EGTs under load, improves throttle response, boosts fuel economy, and restores that unmistakable Cummins diesel rumble.
Key Features
- Premium T409 Stainless Steel: Mandrel-bent 4-inch T409 stainless steel tubing engineered to resist severe exhaust heat, road salt, and long-term rust.
- Sharply Drop Towing EGTs: Accelerates exhaust gas flow right after the turbo downpipe, drastically lowering Exhaust Gas Temperatures (EGTs) under heavy loads.
- Kill Regens & DEF System Errors: Permanently eliminates active regeneration cycles and DEF system issues, saving fuel and preventing oil dilution.
- Eliminate DPF & SCR Restrictions: Replaces the heavy, clogged factory DPF, CAT, and SCR (DEF system) mid-section with a smooth 4-inch high-flow straight race pipe.
FAQ
Q: Do I need a delete tuner to run this 4" DPF/SCR race pipe on a 2013–2018 Cummins?
A: Yes. Removing the factory DPF, SCR, and sensors will trigger Check Engine Lights and Limp Mode. A compatible race delete tuner is required to clear fault codes and manage engine parameters.
Q: Do I need to reinstall factory sensors or DEF injectors into this race pipe?
A: No. This is a smooth, straight-pipe design without sensor bungs or DEF ports. Once your ECU is properly tuned for a delete, you simply unplug the factory sensor harness, zip-tie it safely out of the way, and cap or plug any exposed electrical connectors.
Q: Will this race pipe connect to my factory downpipe and rear tailpipe?
A: Yes. It is designed as a direct mid-section replacement that bolts straight to your stock 4" front downpipe outlet and connects seamlessly to your OEM rear tailpipe section.
Q: Do you recommend pairing this race pipe with an EGR Delete Kit?
A: Highly recommended. While this race pipe frees exhaust flow, an EGR Delete Kit stops hot, soot-heavy gases from entering your intake manifold. Combining both keeps intake air cool and clean, prevents valve soot buildup, and offers complete engine protection.
