Toyota GT86 Downpipes – Catted & Decat Performance Exhaust Upgrades

Toyota GT86 Downpipes – Unlock the True Potential

The Toyota GT86 is an enthusiast’s favourite for its lightweight chassis, balanced handling, and responsive FA20 boxer engine. However, the restrictive OEM downpipes limit exhaust flow and hold back potential performance gains. Upgrading to high-performance Toyota GT86 downpipes is one of the most effective modifications to improve throttle response, increase horsepower, and achieve a sportier exhaust note.

Why Upgrade Your Toyota GT86 Downpipes?

The stock downpipes are designed with emissions compliance and noise regulations in mind, which restricts performance. Installing performance downpipes offers several benefits:

• Increased horsepower and torque – high-flow designs reduce backpressure, unlocking additional performance.
• Better throttle response – faster exhaust flow delivers sharper acceleration and more engaging drivability.
• Enhanced exhaust tone – catted downpipes provide a refined, sporty sound, while decat downpipes deliver a more aggressive, motorsport-inspired roar.
• Lower exhaust gas temperatures – improved thermal management supports engine longevity under spirited driving.
• Perfect for ECU tuning – essential for Stage 1, Stage 2, and turbo conversion builds.

Catted vs. Decat Toyota GT86 Downpipes

Catted Downpipes

Catted GT86 downpipes feature high-flow sports catalytic converters, balancing emissions compliance with improved performance. Ideal for street-driven cars in regions with emissions testing.

Decat Downpipes

Decat GT86 downpipes remove catalytic converters entirely, maximizing exhaust flow and raw power gains. Best suited for track-focused builds or regions without emissions restrictions.

Material Options: Stainless Steel & Titanium

Our Toyota GT86 performance downpipes are built from premium materials to ensure long-lasting durability and optimal performance:

• Stainless steel downpipes – corrosion-resistant, strong, and ideal for most performance builds.
• Titanium downpipes – ultra-lightweight, exceptional heat resistance, and a premium motorsport finish.

Toyota GT86 Model Compatibility

We offer performance downpipes for all Toyota GT86 configurations and tuning levels:

• GT86 FA20 2.0L NA Downpipes – optimized for naturally aspirated setups, improving flow and exhaust tone.
• GT86 Turbo Conversion Downpipes – engineered for boosted builds, supporting hybrid turbo and high-boost applications.
• GT86 Supercharged Downpipes – designed for supercharger kits, improving power delivery and efficiency.

Performance Gains with Toyota GT86 Downpipes

Replacing restrictive OEM downpipes with performance downpipes yields noticeable performance improvements:

• +8–15 HP for naturally aspirated setups.
• +25–50 HP on turbocharged or supercharged builds.
• Improved torque for stronger mid-range power delivery.
• Sharper throttle response and smoother exhaust flow.

Choosing the Right Diameter

Pipe diameter plays a crucial role in balancing power and drivability:

• 2.5-inch downpipes – ideal for stock or lightly tuned engines.
• 3-inch downpipes – recommended for turbocharged or supercharged setups requiring higher exhaust flow.

All our Toyota GT86 downpipes are designed for direct bolt-on installation, using OEM-style flanges and fittings for a seamless upgrade.

Build Quality & Engineering

Each performance downpipe is designed to meet the highest motorsport standards for reliability and precision:

• Mandrel-bent tubing ensures unrestricted exhaust flow.
• Precision TIG welding guarantees strength and leak-free durability.
• High-quality stainless steel or titanium construction withstands extreme conditions.
• OEM-style brackets and fittings ensure perfect integration.

Tuning Potential

Pairing your Toyota GT86 downpipes with ECU tuning unlocks the engine’s full potential:

• Optimized fuel mapping and boost control for turbo builds.
• Increased horsepower and torque across the rev range.
• Customizable exhaust tones depending on catted or decat configuration.
• Essential for Stage 2 and Stage 3 high-performance applications.

Daily Driving vs Track Builds

For daily-driven GT86 models, catted downpipes deliver improved performance while maintaining emissions compliance. For dedicated track cars, decat downpipes provide maximum exhaust flow, aggressive sound, and full tuning flexibility.

Conclusion

Upgrading your Toyota GT86 with performance downpipes is one of the most effective ways to enhance power, improve throttle response, and achieve a sportier exhaust note. Whether you choose catted downpipes for refined street use or decat downpipes for maximum performance, our range of Toyota GT86 downpipes guarantees premium quality, precision fitment, and proven gains on both road and track.
