Audi TTRS Downpipes – Catted & Decat Performance Exhaust Upgrades

Audi TTRS Downpipes – Unlock the 2.5 TFSI’s Full Potential

The Audi TTRS, powered by the iconic 2.5 TFSI five-cylinder engine, is one of the most celebrated performance cars in the Audi Sport lineup. While it delivers impressive power straight from the factory, the restrictive OEM downpipe limits its true potential. Upgrading to a performance Audi TTRS downpipe is one of the most effective modifications to increase horsepower, improve turbo spool, and deliver a more aggressive exhaust tone.

Why Upgrade to a Performance Audi TTRS Downpipe?

The stock downpipe is designed with emissions compliance and noise reduction in mind, but this comes at the expense of turbo efficiency and overall performance. Replacing it with a high-flow Audi TTRS downpipe offers several key benefits:

• Increased horsepower and torque – reduced backpressure allows the engine to breathe more freely.
• Faster turbo spool – less lag, sharper throttle response, and improved acceleration.
• Enhanced exhaust sound – catted downpipes provide a sporty, refined tone, while decat downpipes deliver a raw, motorsport-inspired roar.
• Lower exhaust gas temperatures – better heat management under demanding driving conditions.
• Perfect for ECU tuning – an essential upgrade for Stage 1, Stage 2, and hybrid turbo builds.

Types of Audi TTRS Downpipes

We provide a wide selection of Audi TTRS downpipes tailored to different driving styles and tuning goals:

Catted Audi TTRS Downpipes

Catted downpipes feature a high-flow sports catalytic converter, combining improved performance with emissions compliance. Ideal for daily drivers in regions requiring emissions testing.

Decat Audi TTRS Downpipes

Decat downpipes remove the catalytic converter entirely, delivering maximum exhaust flow and peak performance. Best suited for track-focused builds and areas without emissions restrictions.

Material Options: Stainless Steel & Titanium

The choice of material affects durability, heat resistance, and weight:

• Stainless steel downpipes – highly durable, corrosion-resistant, and cost-effective.
• Titanium downpipes – ultra-lightweight with excellent thermal properties and a premium motorsport finish.

Engine Compatibility

Our Audi TTRS downpipes are designed for perfect fitment and compatibility with various platforms using the 2.5 TFSI engine:

• Audi TTRS 8S 2.5 TFSI Downpipes – ideal for Stage 1, Stage 2, and hybrid turbo builds.
• Audi RS3 2.5 TFSI Downpipes – cross-platform compatibility for similar powertrains.

Performance Gains with Audi TTRS Downpipes

Installing a performance Audi TTRS downpipe provides significant gains, especially when paired with tuning:

• +20–40 HP with a downpipe upgrade alone.
• +50–80 HP combined with Stage 2 ECU remapping.
• Increased torque delivery across the entire powerband.
• Sharper throttle response and reduced turbo lag.

Choosing the Right Diameter

Downpipe diameter plays a crucial role in optimizing performance:

• 2.75-inch downpipes – perfect for mild Stage 1 upgrades.
• 3-inch downpipes – ideal for Stage 2, hybrid turbo setups, and high-boost applications.

All our Audi TTRS downpipes are designed for direct bolt-on installation, ensuring seamless fitment without additional modifications.

Build Quality & Engineering

Our performance Audi TTRS downpipes are engineered to the highest standards:

• Mandrel-bent tubing for smooth, unrestricted exhaust flow.
• Precision TIG welding for superior durability.
• OEM-style flanges and gaskets ensure perfect integration.
• Available in both resonated and non-resonated configurations.

Tuning Potential

Pairing your Audi TTRS downpipe with ECU tuning unlocks its full performance potential:

• Significant increases in horsepower and torque.
• Improved boost control and optimized fueling strategies.
• Custom exhaust tones based on your catted or decat setup.

Daily Driving vs Track Builds

For street-driven builds, catted downpipes strike the perfect balance between performance and emissions compliance. For track-focused cars, decat downpipes maximize power, improve top-end response, and deliver an aggressive motorsport-inspired tone.

Conclusion

Upgrading to a performance Audi TTRS downpipe is one of the best ways to unlock your car’s true potential. Whether you opt for a catted or decat configuration, our selection of Audi TTRS downpipes guarantees premium build quality, precision fitment, and proven power gains.
