Audi RS6 Downpipes – Catted & Decat Performance Exhaust Upgrades

Audi RS6 Downpipes – Unleash the Full Potential of Your Twin-Turbo Engine

The Audi RS6 is the ultimate high-performance wagon and sedan, offering an unmatched blend of practicality and power. Across its generations – including the C5 4.2 BiTurbo V8, C6 5.0 V10 BiTurbo, C7 4.0 TFSI V8 and C8 4.0 TFSI V8 – the RS6 delivers incredible performance. However, restrictive OEM downpipes limit the true potential of these engines. Upgrading to performance Audi RS6 downpipes is one of the most effective ways to increase horsepower, improve throttle response and achieve an aggressive motorsport-inspired exhaust note.

Why Upgrade to a Performance Audi RS6 Downpipe?

Factory downpipes are designed to meet emissions and noise regulations but significantly restrict exhaust gas flow. Replacing them with high-flow RS6 downpipes provides multiple benefits:

• Significant horsepower & torque gains – reduce backpressure and unleash hidden performance.
• Faster turbo spool – improved flow delivers quicker throttle response and sharper acceleration.
• Enhanced exhaust sound – catted downpipes deliver a refined sporty tone, while decat downpipes produce an aggressive, motorsport-inspired roar.
• Lower exhaust gas temperatures – optimized thermal efficiency protects turbochargers and engine components under high load.
• Perfect for ECU tuning – essential for Stage 1, Stage 2 and hybrid turbo setups.

Types of Audi RS6 Downpipes

Our range of Audi RS6 downpipes is designed for different performance goals and driving styles:

Catted Audi RS6 Downpipes

Catted downpipes integrate a high-flow sports catalytic converter, providing a balance between emissions compliance and improved performance. Ideal for daily-driven RS6 models in regions with strict testing requirements.

Decat Audi RS6 Downpipes

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

Material Options: Stainless Steel & Titanium

The choice of material affects performance, durability and weight:

• Stainless steel downpipes – robust, corrosion-resistant and ideal for most builds.
• Titanium downpipes – ultra-lightweight, superior thermal management and a premium motorsport finish.

Engine Compatibility by Generation

Our Audi RS6 downpipes are engineered for multiple generations and engine configurations:

• Audi RS6 C5 Downpipes – designed for the 4.2 BiTurbo V8 platform.
• Audi RS6 C6 Downpipes – optimized for the 5.0 V10 BiTurbo engine.
• Audi RS6 C7 Downpipes – developed for the 4.0 TFSI twin-turbo V8.
• Audi RS6 C8 Downpipes – built for the latest 4.0 TFSI twin-turbo V8 powerhouse.

Performance Gains with Audi RS6 Downpipes

Upgrading to performance RS6 downpipes delivers immediate and measurable performance improvements:

• +30–50 HP with downpipes alone.
• +60–100 HP when combined with Stage 2 ECU remapping.
• Substantial torque gains for improved mid-range pull and acceleration.
• Sharper throttle response and reduced turbo lag.

Choosing the Right Diameter

The optimal downpipe diameter depends on your setup and tuning goals:

• 3-inch downpipes – perfect for Stage 1 and Stage 2 applications.
• 3.5-inch downpipes – recommended for hybrid turbos, big turbo builds and extreme tuning setups.

All Audi RS6 downpipes are designed for direct bolt-on installation, requiring no cutting or welding.
