Toyota Supra Downpipes – Catted & Decat Performance Exhaust Upgrades

Toyota Supra Downpipes – Unleash the Full Potential of Your Engine

The Toyota Supra is an icon of performance, combining cutting-edge engineering with thrilling driving dynamics. Whether you drive the legendary A80 2JZ-GTE twin-turbo or the latest A90/A91 3.0L turbocharged models, the restrictive OEM downpipes hold back your car’s true potential. Upgrading to high-performance Supra downpipes is one of the most effective ways to unlock hidden horsepower, improve turbo response, and achieve a more aggressive exhaust sound.

Why Upgrade Your Toyota Supra Downpipes?

The stock downpipes are designed for emissions and noise compliance, which limits exhaust flow and turbo efficiency. Installing performance downpipes delivers multiple benefits:

• Increased horsepower and torque – high-flow designs reduce backpressure, maximizing engine performance.
• Faster turbo spool – optimized flow sharpens throttle response and reduces turbo lag.
• Enhanced exhaust tone – catted downpipes deliver a sporty yet refined sound, while decat downpipes unleash a motorsport-inspired roar.
• Lower exhaust gas temperatures – better thermal efficiency helps protect turbochargers and critical components under load.
• Perfect for ECU tuning – essential for Stage 1, Stage 2, and hybrid turbo builds.

Catted vs. Decat Toyota Supra Downpipes

Catted Downpipes

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

Decat Downpipes

Decat Supra downpipes remove catalytic converters entirely, delivering maximum exhaust flow and raw performance. Recommended for track-focused builds and unrestricted environments.

Material Options: Stainless Steel & Titanium

Our Toyota Supra downpipes are built using premium-grade materials for durability, performance, and heat resistance:

• Stainless steel downpipes – strong, corrosion-resistant, and ideal for most performance applications.
• Titanium downpipes – ultra-lightweight, superior heat dissipation, and a motorsport-inspired finish.

Toyota Supra Model Compatibility

We offer performance downpipes for all Toyota Supra generations:

• GR Supra A90 / A91 Downpipes – designed for the 3.0L turbocharged B58 engine, delivering significant gains when paired with ECU tuning.
• GR Supra 2.0 Downpipes – optimized for the 2.0L turbocharged B48 engine, enhancing power and response.
• MK4 Supra A80 Downpipes – engineered for the legendary 2JZ-GTE twin-turbo engine to support high-boost builds.
• MK3 Supra MA70 Downpipes – designed for 7M-GTE turbo engines, improving flow and exhaust tone.

Performance Gains with Toyota Supra Downpipes

Upgrading to performance downpipes delivers significant improvements across all Supra models:

• +30–50 HP with downpipes alone on stock turbo setups.
• +70–120 HP when combined with Stage 2 ECU tuning and intake upgrades.
• Improved mid-range torque for stronger in-gear acceleration.
• Sharper throttle response and reduced turbo lag.

Choosing the Right Diameter

The correct pipe diameter ensures optimal power delivery and drivability:

• 2.5-inch downpipes – ideal for Stage 1 ECU tunes and mild performance setups.
• 3-inch downpipes – recommended for Stage 2 builds, hybrid turbos, and high-boost applications.
• 3.5-inch downpipes – perfect for extreme builds and maximum flow requirements.

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

Build Quality & Engineering

Each performance downpipe is precision-engineered to deliver superior strength, durability, and efficiency:

• Mandrel-bent tubing ensures smooth, unrestricted flow.
• Precision TIG welding guarantees leak-free joints and long-lasting reliability.
• Premium stainless steel or titanium construction withstands extreme heat and pressure.
• OEM-style mounting brackets and fittings ensure perfect fitment.

Tuning Potential

Pairing your Toyota Supra downpipes with ECU tuning unlocks the platform’s full potential:

• Massive gains in horsepower and torque for both stock and hybrid turbo builds.
• Optimized boost control and fueling strategies.
• Custom exhaust sound profiles based on catted or decat configurations.
• Essential for Stage 2 and Stage 3 big-turbo applications.

Daily Driving vs Track Builds

For daily-driven Supras, catted downpipes provide balanced performance and emissions compliance. For dedicated track cars, decat downpipes deliver maximum flow, aggressive sound, and support for extreme tuning levels.

Conclusion

Upgrading your Toyota Supra with performance downpipes is the ultimate step to unlocking hidden power, improving turbo response, and achieving a more aggressive exhaust tone. Whether you choose catted downpipes for refined street performance or decat downpipes for unrestricted motorsport gains, our range of Toyota Supra downpipes guarantees premium quality, precision fitment, and proven results.
