FITMENT
- 2010-2012 6.7L Dodge Ram Cummins 2500 / 3500 Turbo Diesel.
DESCRIPTION
Product Overview
- The factory exhaust on 2010–2012 Dodge Ram 6.7L Cummins trucks creates a massive bottleneck. From the restrictive stock downpipe to the heavy DPF, catalytic converter, and chambered muffler, the OEM setup traps intense thermal energy, slows down turbo spool, and triggers frequent fuel-wasting regen cycles.
- The 4" Turbo-Back DPF Delete Race Exhaust System is the ultimate top-to-bottom performance upgrade. Engineered from smooth, mandrel-bent 4" T409 SS, this kit replaces every inch of restrictive OEM exhaust piping directly behind the turbocharger. By maximizing exhaust gas velocity from the source, it sharply drops EGTs, restores instant throttle response, and unleashes the iconic Cummins turbo whistle and exhaust rumble.
Key Features
- Premium T409 Stainless Steel: Full 4" mandrel-bent T409 stainless steel piping provides high-heat resistance, long-term rust protection, and structural durability.
- Maximum EGT Reduction: Flushes out backpressure at the turbo turbine wheel, allowing hot exhaust gases to evacuate immediately to drastically lower towing EGTs.
- Eliminate Power-Robbing Regens: Permanently ends active DPF regeneration cycles, protecting engine oil from fuel dilution while boosting fuel efficiency (MPG).
- Unleash Authentic Cummins Whistle: Straight-pipe race design delivers maximum turbo spool sound, crisp throttle response, and a deep, aggressive inline-6 diesel roar.
FAQ
Q: What is the difference between a Turbo-Back system and a DPF-Delete mid-pipe?
A: DPF-delete mid-pipe only replaces the middle emissions section while keeping your stock downpipe and rear tailpipe. A Turbo-Back system replaces everything from the turbo outlet to the rear tailpipe, providing maximum airflow and the greatest reduction in EGTs.
Q: Will this system fit all cab and bed configurations?
A: Yes. The kit includes straight extension pipes to accommodate various wheelbases (Crew Cab Short Bed, Mega Cab, Long Bed, etc.). Minor trimming of the extension pipe section may be required during fitment depending on your exact wheelbase.
Q: How loud is a 4" turbo-back straight-pipe on a 6.7L Cummins?
A: It is significantly louder than stock. Deleting the DPF, CAT, and muffler produces a very distinct VGT turbo whistle at idle and a loud, throaty inline-6 roar under hard acceleration.
Q: Do you recommend installing an EGR Delete Kit alongside this 4" Turbo-Back system?
A: Highly recommended. While this turbo-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.
