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: What is the advantage of a 5" Turbo-Back exhaust over a 4" Dp-Back system?
A: 5" system offers significantly higher exhaust volume. It is the best choice for trucks running custom tunes, upgraded turbos, or heavy towing rigs where maximizing airflow and lowering EGTs as fast as possible are top priorities.
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: Does installing a 5" Turbo-Back exhaust improve turbo spool time?
A: Yes. Replacing the restrictive factory downpipe and emissions core with a 5-inch straight path drastically reduces turbine exhaust backpressure. This allows your VGT turbo wheel to spin up faster, giving you quicker throttle response and reduced turbo lag under load.
Q: Can I add a 5" performance muffler to this system later if I want to reduce drone?
A: Yes. The system is completely modular. If you ever decide the raw straight-pipe sound is too loud for daily driving, you can easily unclamp a section of the 5-inch straight extension pipe and slip in any standard 5" ID/OD high-flow performance muffler.
