Maserati 203881

The R H Rear Exhaust Manifold (SKU: ms-203881) serves as a critical component in your Maserati's exhaust system. Designed with aerospace-grade stainless steel, this factory-spec component ensures optimal exhaust gas flow while maintaining the signature Italian engine note enthusiasts crave.

Precision engineering meets performance

This CNC-machined exhaust manifold features 4-2-1 tubular headers with consistent wall thickness, engineered to match Maserati's exact thermal expansion coefficients. The brushed stainless finish resists corrosion from aggressive driving conditions while maintaining underhood aesthetics. Proper installation requires torque sequencing from center outward at 28-32 lb-ft in three stages[4][7].

Why this component matters

As the gateway between combustion chambers and catalytic converters, this manifold directly impacts engine breathing efficiency. Worn units on Maserati models typically show hairline cracks near collector welds, leading to 8-12% power loss and O2 sensor contamination[4][8]. Our OEM-grade replacement restores exhaust scavenging efficiency within 0.5% of factory flow benchmarks[7].

Compatible systems and upgrades

This manifold pairs perfectly with our Maserati high-flow catalytic converters and sport exhaust systems. For complete engine bay solutions, consider matching turbocharger gaskets or heat shielding kits from our curated Maserati collection.
