Audi RS5 Downpipes – Catted & Decat Performance Exhaust Upgrades

Audi RS5 Downpipes – Unleash the True Power of Your V8 or V6 TFSI Engine

The Audi RS5 is a high-performance coupe and sportback, blending luxury with extreme power and precision engineering. Across its generations – from the B8 4.2 FSI V8 to the latest B9 2.9 TFSI twin-turbo V6 – the RS5 delivers thrilling performance in stock form. However, restrictive OEM downpipes limit the full potential of these engines. Upgrading to performance Audi RS5 downpipes is one of the most effective ways to increase horsepower, improve throttle response and transform the exhaust sound.

Why Upgrade to a Performance Audi RS5 Downpipe?

The factory downpipes are designed to meet emissions and noise regulations, but this restricts exhaust flow and reduces power. Installing high-flow RS5 downpipes offers several key benefits:

• Increased horsepower & torque – reduce backpressure and improve exhaust gas flow for maximum gains.
• Faster turbo spool (B9 models) – quicker boost response delivers sharper acceleration.
• Enhanced exhaust tone – catted downpipes provide a refined, sporty sound, while decat downpipes deliver an aggressive, motorsport-inspired roar.
• Lower exhaust gas temperatures – better thermal efficiency protects engine components during high-performance driving.
• Perfect for ECU tuning – essential for Stage 1, Stage 2 and hybrid turbo setups.

Types of Audi RS5 Downpipes

We offer a full range of Audi RS5 downpipes designed to match your tuning goals and driving style:

Catted Audi RS5 Downpipes

Catted downpipes feature a high-flow sports catalytic converter that balances emissions compliance with improved performance. Perfect for street-driven RS5s and areas with strict emissions testing.

Decat Audi RS5 Downpipes

Decat downpipes remove the catalytic converter entirely, maximizing exhaust flow and achieving peak power gains. Recommended for track-focused builds and off-road performance applications.

Material Options: Stainless Steel & Titanium

The material you choose impacts performance, weight and heat management:

• Stainless steel downpipes – durable, corrosion-resistant and cost-effective, perfect for most performance builds.
• Titanium downpipes – ultra-lightweight, superior heat resistance and a premium motorsport finish.

Engine Compatibility by Generation

Our Audi RS5 downpipes are engineered for both naturally aspirated and twin-turbo engines across multiple generations:

• Audi RS5 B8 Downpipes – optimized for the high-revving 4.2 FSI V8 engine.
• Audi RS5 B9 Downpipes – designed for the 2.9 TFSI twin-turbo V6 platform.

Performance Gains with Audi RS5 Downpipes

Installing performance RS5 downpipes delivers immediate improvements across all RS5 generations:

• +20–35 HP with downpipes alone.
• +45–80 HP when combined with Stage 2 ECU tuning.
• Significant torque gains for stronger mid-range acceleration.
• Sharper throttle response and reduced turbo lag (for B9 twin-turbo models).

Choosing the Right Diameter

Selecting the optimal downpipe diameter is key to maximizing performance:

• 2.75-inch downpipes – ideal for Stage 1 setups and lightly tuned builds.
• 3-inch downpipes – perfect for Stage 2 tuning and hybrid turbo setups.
• 3.5-inch downpipes – recommended for big turbo conversions and extreme power builds.

All Audi RS5 downpipes are engineered for direct bolt-on installation, requiring no cutting or welding for perfect fitment.
