- This kit is designed for standard leaf-spring pickup truck configurations.
- Does NOT fit trucks equipped with the factory-optional Rear Air Suspension or commercial Cab & Chassis (4500/5500) models.
DESCRIPTION
Product Overview
-
The factory emissions system on 2013–2018 Dodge Ram 6.7L Cummins trucks creates extreme exhaust restriction. From the tight stock downpipe to the heavy DPF, catalytic converter, SCR (DEF) unit, and chambered muffler, heat is trapped directly behind the turbo, robbing horsepower and choking airflow.
- The 5" Turbo-Back DPF & SCR Delete Race Exhaust System is the ultimate top-to-bottom airflow upgrade. It completely eliminates all emissions restrictions and muffler backpressure. This setup yields maximum cooling for your turbocharger, restores instant throttle response, boosts fuel economy, and delivers an unmistakable 5" straight-pipe Cummins roar.
Key Features
- Premium T409 Stainless Steel: Full mandrel-bent 5" T409 stainless steel construction built to handle extreme thermal expansion, road salt corrosion, and long-term durability.
- Unleash Raw VGT Turbo Screamer Sound: Complete 5-inch straight-pipe design creates deep low-end diesel thunder and a loud, aggressive twin-spool turbo whistle under load.
-
Maximum Heat Evacuation: Eliminates backpressure right at the turbo wheel, allowing hot gases to flush out instantly for the sharpest drop in Exhaust Gas Temperatures (EGTs) under heavy towing or high-HP tuning.
- Kill Regens & DEF System Failures: Permanently stops active regeneration cycles and DEF system errors, restoring engine efficiency, improving MPG, and preventing fuel dilution in oil.
FAQ
Q: Does the 5" performance muffler restrict exhaust flow or increase backpressure?
A: No. It features a full 5-inch straight-through core design. Exhaust gases pass straight through without obstruction, tuning out harsh sound frequencies without slowing down exhaust velocity or trapping heat.
Q: What is the advantage of a 5" Turbo-Back exhaust over a 4" system?
A: 5" exhaust offers significantly higher internal volume, making it the ideal choice for high-horsepower tunes, heavy towing setups, or builds where lowering EGTs as fast as possible is a top priority.
Q: Do I need a delete tuner to run this 5" turbo-back exhaust on a 2013–2018 Cummins?
A: Yes. Removing the factory downpipe, DPF, SCR, and sensors will trigger Check Engine Lights and Limp Mode. A compatible race delete tuner is required to bypass emissions codes and manage engine parameters.
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.
