LAMBORGHINI HURACAN PERFORMANTE Exhaust Rear Silencer

The Rear Silencer (Muffler) for the Lamborghini Huracán Performante is a specialized component that differs significantly from the standard LP610-4 or even the later Evo models. It was designed specifically to support the Performante’s higher power output ($640\text{ CV}$) and to be as lightweight as possible.

1. Technical Identification & Design

• Part Number: The core assembly usually starts with 4T0251051 (with suffixes like M or L for the Performante-specific tuning).

• High-Mount Exit: Unlike the standard Huracán, the Performante silencer is designed for the high-mounted center-exit exhaust. The pipes exit directly through the rear mesh, reducing backpressure and saving weight by shortening the piping.

• Material: Constructed from a high-nickel alloy (Inconel-type properties) or specialized lightweight stainless steel to withstand the extreme heat generated by the $5.2\text{L}$ V10.

• Internal Valves: Features vacuum-actuated bypass valves that open in Sport and Corsa modes, effectively bypassing the internal muffling chambers for a “straight-pipe” sound.
