Scorpion Turbo Downpipe, Audi, A4 (B9) Quattro 2.0 TFSi, 2016-2024

Unlock the true performance potential of your engine with the Scorpion De-cat downpipe. Engineered for maximum exhaust gas flow and minimal restriction, this premium downpipe is the ultimate upgrade for track days and motorsport applications. By removing the restrictive factory catalytic converter, this downpipe allows your turbocharger to spool faster, significantly improving throttle response and increasing overall horsepower and torque.

Maximum Performance and Flow

For automotive enthusiasts seeking the absolute pinnacle of engine performance, the Scorpion De-cat downpipe delivers uncompromising results. The factory catalytic converter is typically the most restrictive component in a modern turbocharged vehicle's exhaust system, creating significant backpressure that chokes engine output and dampens exhaust acoustics. By replacing this restrictive bottleneck with our high-flow de-cat downpipe, you allow the exhaust gases to exit the engine with minimal resistance. This dramatic increase in flow velocity allows the turbocharger to spool up significantly faster, translating to instantaneous throttle response and a massive reduction in turbo lag. The performance gains are substantial, with noticeable increases in both peak horsepower and mid-range torque, transforming the driving dynamics of your vehicle. Crafted from premium T304 aerospace-grade stainless steel, this downpipe is engineered to endure the extreme thermal stresses of high-performance driving and track use. The precision TIG-welded construction ensures maximum strength and longevity, while the smooth, mandrel-bent pipework optimizes gas flow dynamics. Beyond the performance benefits, the installation of this de-cat downpipe dramatically alters the vehicle's acoustic profile, unleashing a raw, aggressive motorsport soundtrack that will thrill any driving enthusiast. Please be aware that removing the primary catalytic converter is intended for off-road and motorsport applications. It will likely trigger an Engine Management Light (EML) due to altered emissions readings, making a Stage 2 ECU remap highly recommended to optimize fueling parameters and clear any diagnostic codes.

Key Features & Benefits
