FITMENT
- 2010–2012 6.7L Dodge Ram Cummins 2500 / 3500 Turbo Diesel.
DESCRIPTION
Product Overview
-
Factory 2010–2012 6.7L Cummins engines can suffer from exhaust restriction and intake contamination caused by the factory emissions system. The stock DPF and catalytic converter increase exhaust backpressure, while the EGR system and throttle valve introduce soot and restrict airflow into the intake.
- The Cummins Package addresses these factory restrictions with a 4" DPF/CAT delete race pipe and complete EGR valve & cooler delete. This upgrade improves exhaust and intake airflow, reduces soot buildup, and helps your 6.7L Cummins operate more efficiently.
Key Features
- High-Flow DPF/CAT Delete Race Pipe: Replaces restrictive factory DPF and catalytic converter components with a smooth pipe, improving exhaust flow and reducing restriction under load.
- High-Flow Throttle Valve Delete Tube: Replaces the restrictive factory throttle valve assembly with a smoother airflow path for improved intake efficiency.
- Improved Turbo Response & Exhaust Sound: Reduced exhaust restriction helps improve turbo response while delivering a deeper, more aggressive diesel exhaust tone.
- High-Flow Throttle Valve Delete Tube: Replaces the restrictive factory throttle valve assembly with a smoother airflow path for improved intake efficiency.
- EGR Cooler Delete: Removes the factory EGR valve and cooler assembly to help reduce soot buildup, intake contamination, and common EGR-related issues.
FAQ
Q: What is the main performance benefit of installing this complete 2010–2012 kit?
A: It removes both intake and exhaust bottlenecks. You'll experience faster turbo spool, lower EGTs during towing, total elimination of fuel-wasting DPF regens, and a clean, soot-free intake tract.
Q: Will removing the factory throttle valve affect engine shutdown or cause rough shut-off?
A: No. With proper custom ECM delete tuning, the engine will shut down smoothly without the factory throttle valve. Replacing it with our high-flow delete tube eliminates a major intake airflow bottleneck without sacrificing shutdown comfort.
Q: Can I keep my factory muffler when installing this 4" DPF race pipe?
A: Yes. This 4" race pipe replaces only the factory DPF and catalytic converter assembly, bolting directly upstream of your stock rear tailpipe and muffler section for a clean, direct fit.
Q: Will removing the DPF and EGR increase diesel exhaust odor?
A: Yes, slightly. Because the catalytic converter and DPF are replaced with a straight 4" race pipe, you will notice a classic raw diesel exhaust smell at idle, which is standard for off-road/race deleted trucks.
