Audi S7 Downpipes – Catted & Decat Performance Exhaust Upgrades

Audi S7 Downpipes – Unleash the Full Potential of Your Twin-Turbo Engine

The Audi S7 is a perfect balance of luxury and performance, combining stunning design with cutting-edge engineering. Across its generations, the S7 has featured two powerful engines: the 4.0 TFSI twin-turbo V8 in the C7/C7.5 (2012–2018) and the 2.9 TFSI twin-turbo V6 in the C8 (2019+). While both deliver exceptional stock performance, the restrictive OEM downpipes limit exhaust flow, turbo response, and potential power. Upgrading to performance Audi S7 downpipes is one of the most effective modifications to unlock hidden horsepower and achieve a deeper, motorsport-inspired exhaust note.

Why Upgrade to Performance Audi S7 Downpipes?

The factory downpipes are designed for emissions compliance and sound control, but they significantly restrict exhaust flow. Installing a set of high-flow Audi S7 downpipes offers several benefits:

• Substantial horsepower and torque gains – better exhaust flow reduces backpressure and improves engine breathing.
• Faster turbo spool – crucial for both the 4.0 TFSI V8 and 2.9 TFSI V6 engines.
• Enhanced exhaust tone – catted downpipes deliver a sporty, refined note, while decat downpipes unleash an aggressive motorsport roar.
• Lower exhaust gas temperatures – improves thermal efficiency and protects key components under load.
• Perfect for ECU tuning – essential for Stage 1, Stage 2, and hybrid turbo setups.

Types of Audi S7 Downpipes

We offer a wide range of Audi S7 downpipes designed to suit different power levels, driving styles, and tuning goals:

Catted Audi S7 Downpipes

Catted downpipes feature high-flow sports catalytic converters, improving exhaust flow while maintaining emissions compliance. Perfect for street-driven cars in regions with emissions testing.

Decat Audi S7 Downpipes

Decat downpipes eliminate catalytic converters entirely, maximizing exhaust flow and peak performance. Ideal for track-focused builds or areas without emissions restrictions.

Material Options: Stainless Steel & Titanium

The choice of material impacts weight, thermal properties, and durability:

• Stainless steel downpipes – durable, corrosion-resistant, and cost-effective; suitable for most builds.
• Titanium downpipes – ultra-lightweight, premium heat resistance, and motorsport-grade finish.

Engine & Model Compatibility

Our Audi S7 downpipes are engineered for perfect fitment across multiple generations and engine types:

• Audi S7 C7 / C7.5 4.0 TFSI Downpipes – optimized for twin-turbo V8 engines, perfect for Stage 2 tuning.
• Audi S7 C8 2.9 TFSI Downpipes – designed for the latest twin-turbo V6 platform, supporting hybrid turbos and high-boost applications.

Performance Gains with Audi S7 Downpipes

Upgrading to performance Audi S7 downpipes provides instant, measurable gains:

• +40–60 HP on stock turbos with downpipes alone.
• +80–120 HP when combined with Stage 2 ECU tuning and supporting mods.
• Sharper throttle response and improved turbo efficiency.
• Deeper, sportier exhaust note with a motorsport character.

Choosing the Right Diameter

Selecting the optimal pipe diameter is key to maximizing gains:

• 2.75-inch downpipes – suitable for Stage 1 tuning and mildly modified setups.
• 3-inch downpipes – ideal for Stage 2, hybrid turbo, and high-performance builds.

All our Audi S7 downpipes are designed for direct bolt-on installation with OEM-style flanges and fittings.

Build Quality & Engineering

Our performance Audi S7 downpipes are manufactured using the highest standards to ensure quality and reliability:

• Mandrel-bent tubing ensures smooth, unrestricted exhaust flow.
• High-grade stainless steel or titanium construction.
• Precision TIG welding guarantees maximum strength and leak-free performance.
• OEM-style flanges and mounting points ensure seamless integration.

Tuning Potential

Combining Audi S7 downpipes with ECU tuning unlocks the full potential of your twin-turbo engine:

• Massive horsepower and torque improvements.
• Optimized boost control and fueling strategies.
• Smoother, more responsive power delivery.
• Custom exhaust profiles based on catted or decat configurations.

Daily Driving vs Track Builds

For street-driven S7s, catted downpipes offer a balance of performance, emissions compliance, and comfort. For track-focused builds, decat downpipes deliver maximum flow, aggressive tone, and uncompromised power.

Conclusion

Upgrading to performance Audi S7 downpipes is one of the most effective ways to improve power, turbo response, and exhaust tone. Whether you choose catted downpipes for everyday drivability or decat downpipes for ultimate motorsport performance, our selection of Audi S7 downpipes guarantees exceptional quality, precise fitment, and proven results.
