Citroën Downpipes – Catted & Decat Performance Exhaust Upgrades

Citroën Downpipes – Unlock the Full Potential of Your Engine

Whether you drive a compact Citroën DS3, a sporty DS4, or a performance-oriented DS7 Crossback, upgrading to a performance downpipe is one of the most effective ways to improve your car’s overall performance. Factory-fitted downpipes are primarily designed to meet emissions and noise regulations, which often restrict exhaust flow and limit your vehicle’s true potential. By replacing the restrictive OEM component with a high-flow Citroën downpipe, you can unleash hidden horsepower, enhance throttle response, and achieve a sportier exhaust tone.

Why Upgrade to a Performance Citroën Downpipe?

Installing a performance downpipe provides a range of benefits for turbocharged petrol and diesel Citroën engines:

• Increased horsepower and torque – optimized exhaust flow reduces backpressure and frees up power.
• Faster turbo spool – improved response, reduced lag, and sharper acceleration.
• Enhanced exhaust tone – catted downpipes provide a refined, sporty sound, while decat downpipes offer a raw, motorsport-inspired roar.
• Lower exhaust gas temperatures – improved heat management during spirited driving.
• Perfect for ECU tuning – essential for Stage 1, Stage 2, and hybrid turbo setups.

Types of Citroën Downpipes

We offer a wide selection of Citroën performance downpipes tailored to different tuning goals and driving preferences:

Catted Citroën Downpipes

Catted downpipes integrate a high-flow sports catalytic converter, improving performance while maintaining emissions compliance. Ideal for daily-driven cars in regions requiring emissions testing.

Decat Citroën Downpipes

Decat downpipes remove the catalytic converter completely, maximizing exhaust flow and top-end performance. Best suited for track builds or regions without emissions restrictions.

Material Options: Stainless Steel & Titanium

The material of your Citroën downpipe directly affects weight, durability, and thermal performance:

• Stainless steel downpipes – durable, corrosion-resistant, and cost-effective.
• Titanium downpipes – ultra-lightweight, heat-resistant, and offering a premium motorsport appearance.

Engine Compatibility

Our Citroën downpipes are designed for seamless fitment across a wide range of petrol and diesel models:

• Citroën DS3 1.6 THP Downpipes – optimized for performance gains in turbocharged petrol engines.
• Citroën DS4 1.6 THP Downpipes – ideal for Stage 1 and Stage 2 ECU tuning.
• Citroën DS7 Crossback 1.6 PureTech Downpipes – designed for the latest-generation petrol engines.
• Citroën 2.0 BlueHDi Downpipes – built for improved torque and efficiency in diesel configurations.

Performance Gains with Citroën Downpipes

Upgrading to a performance Citroën downpipe offers measurable and immediate improvements:

• +10–30 HP with a downpipe upgrade alone.
• +25–50 HP when combined with Stage 2 ECU tuning.
• Enhanced midrange torque for better drivability.
• Sharper throttle response and reduced turbo lag.

Choosing the Right Diameter

Picking the optimal downpipe diameter is key to maximizing exhaust flow and performance:

• 2.5-inch downpipes – perfect for Stage 1 builds and mild tuning.
• 3-inch downpipes – ideal for Stage 2 setups, hybrid turbos, and high-performance configurations.

All our Citroën downpipes are designed for direct bolt-on installation, ensuring seamless fitment without cutting or welding.

Build Quality & Engineering

Every performance Citroën downpipe is built to the highest standards to ensure durability, precision, and efficiency:

• Mandrel-bent tubing ensures smooth, unrestricted exhaust flow.
• Precision TIG welding guarantees strength and leak-free performance.
• OEM-style flanges and fittings ensure perfect integration.
• Available in both resonated and non-resonated configurations.

Tuning Potential

Pairing your Citroën downpipe with ECU tuning unlocks the full potential of your engine:

• Substantial horsepower and torque improvements.
• Optimized boost control and fueling strategies.
• Custom exhaust tones depending on catted or decat configuration.

Daily Driving vs Track Builds

For everyday builds, catted downpipes offer the ideal mix of performance and emissions compliance. For track-focused projects, decat downpipes maximize flow, power, and deliver an aggressive motorsport-inspired tone.

Conclusion

Upgrading to a performance Citroën downpipe is one of the most effective ways to unlock hidden power, improve turbo response, and enhance your car’s exhaust sound. Whether you choose a catted or decat option, our selection of Citroën downpipes ensures premium quality, precise fitment, and proven performance gains. Transform your Citroën today.
