Lamborghini Huracan Manifold Exhaust

Exhaust Manifold (Header) for the Lamborghini Huracán is a high-performance, stainless steel component designed to handle the extreme heat and gas velocity of the 5.2L V10 engine.

Since the engine is a $90^\circ$ V10, there are two separate manifolds: one for the Left Bank (Cylinders 1–5) and one for the Right Bank (Cylinders 6–10).

1. Technical Identification

• Part Numbers: * 4T0253031 (Left Bank)

  • 4T0253032 (Right Bank)

  • Note: Suffixes (like AM, AF, or AJ) vary based on whether it is an early LP610-4 or a later EVO model.

• Material: High-grade heat-resistant stainless steel with integrated thermal shielding.

   

• Design: These are “tuned” 5-into-1 collectors. On the EVO and Performante, the manifolds are slightly lighter and feature optimized internal flow to help reach the $640\text{ CV}$ power rating.

Exhaust manifolds are rarely replaced unless they suffer from cracking or internal baffle failure. Consequently, new units are expensive and often have a lead time.

3. Common 2026 Maintenance Issues

• Heat Shield Rattle: By 2026, many early Huracáns (2015–2017) are experiencing loose rivets on the integrated heat shields. This creates a metallic buzzing sound at specific RPMs.

• Stud/Bolt Failure: The bolts securing the manifold to the cylinder head are subject to thousands of heat cycles. It is very common for these to snap during removal, requiring specialized extraction.

• Catalytic Converter Integration: In some regions, the manifold and the primary catalytic converter are a single welded unit. If the “Cat” fails, you often have to replace the entire manifold assembly.
