Audi RS5 (B9 / B9.5) 2018-2026 2.9T V6 Performance Straight-Through Downpipes - Vortex

Audi RS5 (B9 / B9.5) 2018-2026 2.9T V6 Performance Downpipes - Vortex®

Tame the Heat. Release the RS Symphony.

The Audi RS5 B9 is a precision-engineered beast, but its 2.9T EA839 heart is held back by massive, restrictive factory catalytic converters. Positioned in the "Hot V" of the engine, the stock system traps intense heat near the turbochargers and acts as an acoustic muzzle on the V6 soundtrack.

Vortex® has engineered the ultimate straight-through downpipe solution to eliminate these bottlenecks. By optimizing exhaust gas velocity and reducing backpressure to near-zero, our downpipes allow your RS5 to breathe freely, delivering lightning-fast boost response and the visceral roar that defines the RS lineage.

Vehicle Compatibility & Fitment

Precision-designed for a 100% bolt-on fitment on the B9 RS platform:

Technical Highlights

• Maximizing "Hot V" Efficiency: Our straight-through design facilitates rapid exhaust gas evacuation from the turbos. This leads to significantly lower engine bay temperatures, protecting sensitive components and preventing heat soak during hard driving.

• Instant Power Delivery: Specifically developed for Stage 2 and Stage 3 builds. By removing all factory restrictions, these downpipes provide the hardware foundation for massive horsepower and torque increases, drastically reducing turbo lag.

• The Definitive RS Soundtrack: Transforms the muted factory note into a clear, aggressive, and high-definition mechanical symphony. Expect sharp "barks" on upshifts and a raw, visceral roar at wide-open throttle.

• Premium Material Engineering:

  • T304 Stainless Steel: Precision mandrel-bent for maximum flow and lifelong durability against extreme thermal stress.

  • Grade 5 Aerospace Titanium (Optional): The professional’s choice for weight reduction. Significantly lighter than stock and provides a unique high-frequency metallic "bark."

• Artisanal Craftsmanship: Every Vortex® downpipe features our signature hand-laid TIG fish-scale welding, ensuring structural integrity that can withstand the highest Exhaust Gas Temperatures (EGT).

The Vortex® Quality Standard

"Precision Built. Performance Driven. Secured by Vortex®."

• 🛡️ 2-Year Limited Warranty: We stand behind our engineering. Your Vortex® RS5 downpipes are covered by a 2-year warranty against any material or manufacturing defects.
