R32 VR6 Custom Exhaust Manifold

R32 VR6 CUSTOM PERFORMANCE EXHAUST MANIFOLD (Welded)

This custom performance exhaust manifold is specifically designed for R32 VR6 engines to optimize exhaust gas flow and improve overall engine efficiency and power output. By eliminating the flow restrictions found in OEM exhaust manifolds, it allows the engine to breathe more freely—particularly in the mid and high RPM range.

ADVANCED EXHAUST FLOW DESIGN

OEM exhaust manifolds are primarily designed around cost, emissions, and noise regulations. In performance-oriented and modified engines, this design becomes a significant limitation, especially at higher engine speeds where efficient exhaust gas evacuation is critical.

This custom exhaust manifold features equal-length runners, an optimized collector design, and smooth internal surfaces to ensure faster, more consistent exhaust gas flow. As a result, cylinder-to-cylinder pressure balance is improved and exhaust back pressure is reduced to a minimum.

PERFORMANCE GAINS

• Noticeable power increase in the mid and high RPM range

• Faster turbo spool in turbocharged applications

• Improved throttle response

• Reduced exhaust back pressure

• More stable EGT values and smoother engine operation

An ideal upgrade for high-performance naturally aspirated or turbocharged VR6 engine builds.

OPTIMIZED RUNNER AND COLLECTOR GEOMETRY

Runner diameters and lengths are determined through exhaust flow and resonance calculations to maintain exhaust gas velocity while maximizing scavenging efficiency. The collector geometry is engineered to minimize turbulence at the merge point, ensuring efficient gas evacuation under all load conditions.

DURABLE MATERIALS AND PRECISION FABRICATION

Manufactured from high-temperature–resistant stainless steel or special alloy steel. TIG-welded joints provide excellent durability under extreme heat and vibration. CNC laser-cut flanges ensure precise fitment, superior sealing, and long-term reliability.

PROJECT AND INSTALLATION COMPATIBILITY

• Compatible with OEM-based configurations

• Suitable for turbo conversion projects

• Easily integrated with custom exhaust systems

• Ideal for track, drag racing, and high-performance street use
