The Capristo Racing Test Pipes, also known as Catless Link Pipes or Downpipes, are a pure motorsports component designed to unleash the maximum performance and raw acoustic intensity of the Lamborghini Aventador's naturally aspirated V12 engine.
As a direct replacement for the heavy, restrictive primary catalytic converters, these pipes are crucial for any Aventador owner focused on track use or achieving the highest power output and most aggressive sound.

Performance and Technical Focus
-
Maximum Flow & De-Restriction: These pipes are a straight-through design that completely eliminates the factory's restrictive catalytic converters (typically 600-cell units). This removal drastically reduces exhaust gas backpressure, allowing the V12 to breathe freely.
-
Significant Power Increase: By unlocking maximum exhaust flow, the Catless Downpipes directly contribute to a notable increase in horsepower and torque, particularly in the mid-range and top-end RPMs, transforming the driving dynamics.
-
Material and Weight Reduction: Crafted from Capristo's signature, high-grade T309 (1.4828) Stainless Steel, the test pipes offer superior durability and extreme heat resistance (akin to Inconel used in F1). Critically, they deliver a substantial weight reduction compared to the heavy OEM catalytic converters, enhancing the car's power-to-weight ratio.
-
Direct Fitment: Engineered using advanced 3D scanning and CNC milling, they ensure a precision, bolt-on fitment, connecting directly to the OEM headers and the Capristo or stock rear muffler.
Acoustic Transformation
The primary catalytic converters are a major source of sound suppression. Removing them with Capristo's test pipes results in the most dramatic sound upgrade possible for the Aventador:
-
Unleashed V12 Roar: The sound is transformed from aggressive to pure, unfiltered F1-style racing sound. The volume is significantly louder, with a sharper, more visceral pitch.
-
Exaggerated Backfire and Pops: Under deceleration, the system amplifies the signature crackles, pops, and bangs the V12 is known for, giving the car a truly exotic, untamed character.
Component Details
-
O2 Sensor Bungs: The test pipes include pre-welded and threaded bungs for the Lambda (oxygen) sensors, designed for simple sensor re-installation.
-
Heat Blankets: These components are often available with optional integrated heat blankets (heat shields) to reduce engine bay temperatures and protect surrounding components from the extreme heat generated by the unrestricted exhaust flow.
Compatibility
- Model Compatibility: The pipes are available for most Aventador variants, including the LP700, S LP740, LP750 SV, SVJ LP770, and LP780 Ultimae models (specific part numbers vary by model year and trim).
-
Check Engine Light (CEL): Installation will likely trigger a Check Engine Light (CEL) due to the removal of the catalysts. This typically requires an aftermarket ECU tune or a Capristo CLS-1 Lambda Module (simulator) to prevent the CEL from remaining on.
