Audi RS7 Downpipes – Catted & Decat Performance Exhaust Upgrades

Audi RS7 Downpipes – Unlock the True Potential of the 4.0 TFSI V8

The Audi RS7 is one of the most powerful and technologically advanced models in the Audi Sport lineup, blending luxury with supercar-level performance. Across its generations – from the C7 4.0 TFSI twin-turbo V8 to the latest C8 4.0 TFSI mild-hybrid twin-turbo V8 – the RS7 delivers explosive power and aggressive styling. However, the restrictive OEM downpipes limit the full potential of these engines. Upgrading to performance Audi RS7 downpipes is one of the most effective modifications to increase horsepower, improve throttle response and achieve a motorsport-inspired exhaust tone.

Why Upgrade to a Performance Audi RS7 Downpipe?

Factory-installed downpipes are designed to comply with emissions and noise regulations, but they restrict exhaust gas flow and limit performance. Replacing them with high-flow RS7 downpipes offers several advantages:

• Substantial horsepower & torque gains – optimized exhaust flow reduces backpressure and unlocks hidden performance.
• Faster turbo spool – improved gas flow delivers sharper throttle response and reduced lag.
• Enhanced exhaust tone – catted downpipes provide a deep, refined note, while decat downpipes unleash an aggressive, motorsport-inspired roar.
• Lower exhaust gas temperatures – improved thermal efficiency protects turbos under extreme load conditions.
• Perfect for ECU tuning – essential for Stage 1, Stage 2 and hybrid turbo builds.

Types of Audi RS7 Downpipes

Our selection of Audi RS7 downpipes is designed to match different tuning levels and driving goals:

Catted Audi RS7 Downpipes

Catted downpipes feature a high-flow sports catalytic converter, offering a balance between emissions compliance and enhanced performance. Perfect for street-driven RS7 builds in regions with strict emissions testing.

Decat Audi RS7 Downpipes

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

Material Options: Stainless Steel & Titanium

The construction material affects durability, weight and heat resistance:

• Stainless steel downpipes – robust, corrosion-resistant and cost-effective, ideal for most performance setups.
• Titanium downpipes – ultra-lightweight, exceptional heat dissipation and a premium motorsport finish.

Engine Compatibility by Generation

Our Audi RS7 downpipes are engineered for different generations and engine configurations:

• Audi RS7 C7 Downpipes – optimized for the 4.0 TFSI twin-turbo V8 (2013–2018).
• Audi RS7 C8 Downpipes – designed for the 4.0 TFSI twin-turbo mild-hybrid V8 (2019+).

Performance Gains with Audi RS7 Downpipes

Replacing restrictive OEM downpipes with performance RS7 downpipes delivers immediate power gains:

• +30–55 HP with downpipes alone.
• +70–120 HP when combined with Stage 2 ECU tuning.
• Substantial torque improvements for better mid-range acceleration.
• Sharper throttle response and improved turbo efficiency.

Choosing the Right Diameter

Selecting the optimal downpipe diameter is key to achieving the best performance:

• 3-inch downpipes – ideal for Stage 1 and Stage 2 setups.
• 3.5-inch downpipes – recommended for hybrid turbos, big turbo conversions and extreme power builds.

All Audi RS7 downpipes are designed for direct bolt-on installation, ensuring perfect fitment without cutting or welding.

Build Quality & Engineering

Our performance Audi RS7 downpipes are manufactured using motorsport-grade materials and precision engineering:

• Mandrel-bent tubing ensures smooth, unrestricted exhaust flow.
• Precision TIG welding provides superior strength and reliability.
• OEM-style flanges and fittings guarantee seamless integration.
• High-quality gaskets and installation hardware included.

Tuning Potential

Pairing RS7 downpipes with ECU tuning unlocks the full potential of the 4.0 TFSI twin-turbo V8:

• Optimized boost and fueling strategies for maximum performance.
• Customizable exhaust profiles depending on catted or decat configuration.
• Supports advanced builds, including ethanol tuning, hybrid turbos and big turbo conversions.

Recommended Upgrades
