Porsche 911 (992) Performance Exhaust Manifold – Inconel 718

Upgrade your Porsche 911 (992) with a high-performance exhaust manifold engineered for maximum flow, durability, and weight reduction.

Manufactured using advanced 3D printing technology from aerospace-grade Inconel 718, this manifold delivers superior heat resistance and strength under extreme exhaust temperatures. The flanges are made from heat-resistant stainless steel AISI 321, ensuring long-term reliability and perfect sealing.

Each unit is precisely TIG welded in a dedicated assembly jig, guaranteeing optimal geometry, fitment, and consistent quality — the standard of LEVEL Engineering craftsmanship.

Key Performance Benefits:

• Inconel 718 construction for extreme heat and pressure resistance
• +18% increased turbine inlet cross-sectional area for improved exhaust flow
• Up to 76% reduction in pressure drop for faster turbo response
• Ultra-lightweight design — only 3.85 kg vs 7.60 kg OEM (50% lighter)
• Designed to support individual EGT (exhaust gas temperature) sensors
• Precision TIG welding in specialized fixtures for perfect alignment

Built for Performance

By optimizing exhaust flow and reducing backpressure, this manifold improves turbo efficiency, throttle response, and overall engine performance — ideal for high-performance street builds and track-focused Porsche 992 applications.
