FITMENT
-

- Does NOT fit trucks equipped with factory Rear Air Suspension or commercial Cab & Chassis (4500/5500) models.
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 built to withstand extreme thermal stress, road salt, and long-term corrosion.
- Maximum EGT Reduction: Flushes out trapped heat right behind the downpipe section, allowing exhaust gases to exit instantly to sharply drop EGTs under heavy towing.
- Kill Active Regens & DEF Errors: Permanently eliminates fuel-wasting DPF regeneration cycles and DEF system dependence to improve MPG and prevent crankcase oil dilution.
- Complete DP-Back Airflow: Replaces everything behind the factory downpipe—deleting the restrictive catalytic converter, DPF, SCR (DEF), and OEM muffler.
FAQ
Q: Does the included performance muffler restrict exhaust flow or increase backpressure?
A: No. It features a 4" straight-through core design. Exhaust gases pass through completely unhindered, tuning out unpleasant drone frequencies without slowing exhaust velocity or trapping heat.
Q: What is the difference between a Downpipe-Back pipe and a Turbo-Back system?
A: Downpipe-Back system replaces all exhaust piping and emissions components behind your factory downpipe (retaining your OEM downpipe). A Turbo-Back system replaces the downpipe itself as well, connecting directly to the turbocharger turbine housing.
Q: Do you recommend pairing this downpipe-back race pipe with an EGR Delete Kit?
A: Highly recommended. While this downpipe-back system 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.
Q: Do I need to reinstall factory sensors or DEF injectors into this 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.
