The KNUCKLE PERFORMANCE OM642 Next Gen exhaust manifolds are designed to eliminate the well-known weaknesses of the original manifolds while significantly improving exhaust gas flow and durability.
These manifolds are a direct replacement for the factory units and fit all Mercedes-Benz, Jeep, and Chrysler vehicles equipped with the OM642 3.0 V6 diesel engine.
Key Features
Next Gen high-flow design with greatly improved exhaust flow
Direct bolt-on replacement for original manifolds
Fits all OM642 3.0 V6 diesel engines
High-quality TIG welds
Stainless steel flex joint
No exhaust gas flow restrictions
Why Upgrade?
The original OM642 exhaust manifolds are built using a three-layer pipe construction, which is known to fail over time. The inner pipe spot welds often come loose, leading to:
cracked manifolds
turbocharger damage
power loss and exhaust leaks
Leaking flex pipes are another common and costly issue.
With Knuckle Performance OM642 Next Gen exhaust manifolds, these problems are completely eliminated:
no cracking issues
no loose inner pipes
no flow restrictions
This is the right solution whether you are replacing failed OEM manifolds or building a more powerful and reliable setup.
