Toyota Yaris Downpipes – Catted & Decat Performance Exhaust Upgrades

Toyota Yaris Downpipes – Unlock Your Engine’s Full Potential

The Toyota Yaris is known for its agility, efficiency, and reliability, but when it comes to performance, the restrictive OEM downpipes can hold your car back. Upgrading to high-performance Toyota Yaris downpipes is one of the most effective ways to improve exhaust flow, increase power, and enhance your driving experience.

Why Upgrade to Performance Downpipes?

Replacing stock downpipes with high-flow performance downpipes brings numerous benefits for both turbocharged and naturally aspirated Toyota Yaris models:

• Increased horsepower and torque – improved exhaust flow reduces backpressure, unlocking hidden power.
• Faster turbo spool – optimized flow reduces turbo lag for sharper acceleration.
• Enhanced exhaust tone – catted downpipes deliver a sporty but refined sound, while decat downpipes unleash an aggressive, motorsport-inspired roar.
• Lower exhaust gas temperatures – better thermal efficiency preserves engine and turbo health.
• Perfect for ECU tuning – essential for Stage 1, Stage 2, and hybrid turbo upgrades.

Catted vs. Decat Toyota Yaris Downpipes

Catted Downpipes

Catted downpipes feature high-flow sports catalytic converters to improve performance while keeping emissions compliance intact. Ideal for daily-driven cars where emissions testing applies.

Decat Downpipes

Decat downpipes eliminate catalytic converters entirely, maximizing exhaust flow and engine performance. Perfect for track-focused builds or regions without emissions restrictions.

Material Options: Stainless Steel & Titanium

Our Toyota Yaris performance downpipes are manufactured using premium motorsport-grade materials to withstand extreme conditions:

• Stainless steel downpipes – robust, corrosion-resistant, and ideal for most performance applications.
• Titanium downpipes – ultra-lightweight, superior heat management, and a premium finish for high-end builds.

Toyota Yaris Model Compatibility

We provide performance downpipes for a wide range of Toyota Yaris models:

• Toyota GR Yaris Downpipes – engineered for the 1.6L G16E turbocharged 3-cylinder, designed to handle high boost and ECU tuning.
• Toyota Yaris GRMN Downpipes – optimized for the 1.8L supercharged engine to unlock greater responsiveness and exhaust flow.
• Toyota Yaris Hybrid Downpipes – performance-focused solutions for select hybrid configurations.
• Toyota Yaris Turbo Downpipes – compatible with 1.5L and 1.3L turbocharged petrol engines for improved acceleration.

Performance Gains with Toyota Yaris Downpipes

Installing performance downpipes delivers impressive power and response improvements:

• +15–30 HP on lightly tuned setups.
• +40–70 HP on Stage 2 builds, especially for GR Yaris turbocharged engines.
• Enhanced torque delivery and improved mid-range power.
• Sharper throttle response and faster turbo spool.

Choosing the Right Diameter

Pipe diameter selection depends on your build and tuning level:

• 2.5-inch downpipes – best suited for Stage 1 ECU tuning and mild performance setups.
• 3-inch downpipes – recommended for Stage 2 builds, hybrid turbos, and high-boost applications.

All our Toyota Yaris downpipes are designed for direct bolt-on installation with OEM-style flanges and fittings for a seamless upgrade.

Build Quality & Engineering

Our performance downpipes are built to meet the highest motorsport standards:

• Mandrel-bent tubing for unrestricted exhaust flow.
• Precision TIG welding ensures maximum durability and leak-free joints.
• High-quality stainless steel or titanium construction for extreme reliability.
• OEM-style mounting brackets for perfect fitment.

Tuning Potential

Pairing your Toyota Yaris downpipes with ECU remapping unlocks their full capabilities:

• Substantial horsepower and torque gains, especially on turbocharged engines.
• Optimized boost control and fueling strategies.
• Custom exhaust tone based on catted or decat configurations.
• Essential for Stage 2 and Stage 3 hybrid turbo setups.

Daily Driving vs Track Builds

For street-driven Yaris models, catted downpipes offer a balance of enhanced performance and emissions compliance. For dedicated performance builds, decat downpipes deliver maximum exhaust flow, a raw motorsport sound, and support for high-boost tuning levels.

Conclusion

Upgrading your Toyota Yaris with performance downpipes is one of the most effective ways to unlock hidden power, sharpen turbo response, and achieve a sportier exhaust tone. Whether you choose catted downpipes for refined daily driving or decat downpipes for unrestricted performance, our range of Toyota Yaris downpipes guarantees premium quality, perfect fitment, and proven results on both road and track.
