ATS Diesel 2007.5-2012 Dodge Ram 6.7L Common Rail Cummins 2pc Holset 351VE Flange Exhaust Manifold
The ATS Diesel 2-piece Holset 351VE flange exhaust manifold fits 2007.5-2012 Dodge Ram trucks with 6.7L Cummins diesel engines equipped with the factory HE351VE turbo.
It replaces the stock manifold with a pulse flow design that channels exhaust pulses separately to reduce backpressure and speed turbo response. Drivers see lower exhaust gas temperatures and improved throttle response for towing and daily use.
Key Features
- Two-Piece Assembly: Splits into passenger and driver sides for access in confined engine compartments without pulling the engine.
- Pulse Flow Design: Routes individual cylinder exhaust pulses into dedicated runners to prevent crossover and enhance scavenging efficiency.
- EGT Reduction: Lowers exhaust gas temperatures by up to 150 degrees Fahrenheit during heavy throttle and load conditions.
- High-Silicon Ductile Iron: Cast with thick walls and 1-inch mounting flanges to resist cracking from thermal cycling and vibration.
- Bolt-On Replacement: Aligns precisely with OEM ports and HE351VE turbo flange for plug-and-play installation.
Product Notes
- Confirm your truck has the factory Holset HE351VE variable geometry turbocharger before purchase.
- Combine with a 4-inch downpipe for full exhaust flow benefits and dyno-proven power increases.
- High-temperature powder coat finish resists corrosion in harsh diesel environments.
Installation Notes
- Professional installation recommended.
- Two-piece design installs 50 percent faster than one-piece manifolds using basic hand tools.
- Includes stainless steel studs, gaskets, and hardware. torque to factory specs.

Frequently Asked Questions
- Q: Does this fit 2013 and newer Ram 6.7L Cummins trucks?
- A: No, 2013+ models use a different turbo flange. This manifold matches 2007.5-2012 HE351VE only.
- Q: What alloy is used in construction?
- A: High-silicon molybdenum ductile iron provides better heat retention and crack resistance than factory castings.
- Q: Is engine removal required for installation?
- A: No, the split design allows installation from above and below without disassembly. Expect 4-6 hours labor.
