MST Performance develops purpose-built intake and exhaust components designed to improve airflow, throttle response, and overall engine performance across a wide range of enthusiast platforms. Two standout examples are the MST Catted Downpipe for the Honda Civic Type R and the MST Cold Air Intake System for the Toyota GT86 and Subaru BRZ.

While these products are designed for completely different vehicles, both follow the same performance philosophy: reduce airflow restrictions, optimize the path into or out of the engine, and provide enthusiasts with a straightforward upgrade over the factory system.

MST Catted Downpipe for Honda Civic Type R

The MST HD-TPR03 5" Catted Downpipe is designed for the 2017+ Honda Civic Type R FK8 and FL5, providing a high-flow exhaust solution for the turbocharged Type R platform.

The downpipe combines a 3.5-inch turbo outlet section with an oversized 5-inch catalytic converter section, creating a high-flow exhaust path designed to reduce restriction and backpressure ahead of the rest of the exhaust system.

300-Cell High-Flow Catalytic Converter

At the center of the MST downpipe is a 300-cell metal catalytic converter. This high-flow catalyst provides a performance-oriented alternative to a completely catless downpipe while retaining catalytic-converter functionality.

The larger 5-inch catalytic section is designed to provide additional exhaust-flow capacity, helping the turbocharger evacuate exhaust gases more efficiently.

The result can include:

• Reduced exhaust restriction
• Improved turbocharger response
• Faster spool characteristics
• Improved throttle response
• Stronger power delivery across the RPM range
• Increased exhaust-flow capacity for tuned applications

The downpipe is suitable for both stock and modified vehicles, making it a useful foundation for enthusiasts planning additional performance upgrades.

Designed Around the FK8 and FL5 Type R

The MST HD-TPR03 is designed specifically around the Honda Civic Type R platform and is listed for:

• 2017+ Honda Civic Type R FK8
• 2023+ Honda Civic Type R FL5
• 2.0L turbocharged applications

Because regional specifications and emissions equipment can differ, it is important to verify whether the vehicle is equipped with a GPF/OPF system before ordering.

Catalytic Converter Warranty

MST includes a two-year catalytic converter warranty, subject to the manufacturer's warranty conditions.

The warranty applies when a Check Engine Light is specifically determined to have been caused by the catalytic converter. Warranty claims may require the original downpipe to be returned and inspected before a replacement is provided.

Important Legal Information

The MST HD-TPR03 is intended for off-road and race use only and is not certified as a 50-state emissions-legal component in the United States.

Customers should verify applicable federal, state, and local emissions regulations before purchasing or installing the product.

MST Cold Air Intake for Toyota GT86 & Subaru BRZ

For naturally aspirated Toyota and Subaru sports cars, the MST TY-GT8602 Cold Air Intake System provides a direct-fit airflow upgrade for the 2012–2021 Toyota GT86 and Subaru BRZ 2.0L.

The system is engineered to improve airflow into the FA20 2.0L engine while enhancing throttle response and producing a more aggressive induction sound.

152mm High-Flow Reusable Filter

The MST intake utilizes a large 152mm reusable high-flow air filter designed to provide increased airflow while maintaining effective filtration.

Because the filter is washable and reusable, it can be cleaned periodically rather than replaced after every service interval.

MST recommends:

• Cleaning the filter every 20,000 km
• Replacing the filter after approximately 60,000 km

Following the recommended maintenance schedule helps preserve airflow and filtration performance.

Optimized Intake Design

The MST intake is designed around the specific requirements of the Toyota GT86 and Subaru BRZ rather than functioning as a universal intake system.

Its optimized airflow path helps reduce intake restriction while delivering a more responsive throttle and more pronounced induction sound under acceleration.

MST states that the system can provide approximately 18–24 horsepower in performance gains, depending on the individual vehicle and supporting modifications.

Clear Top Cover

One of the most distinctive features of the MST intake is its clear top cover, which provides a visible look at the high-flow filter and gives the engine bay a more performance-focused appearance.

Combined with the large filter and optimized intake design, the system adds both functional airflow improvements and a more engaging visual presentation.

Direct-Fit Performance Upgrades

Both MST products are designed around specific vehicle platforms rather than requiring universal or heavily customized installation.

The Civic Type R downpipe focuses on improving exhaust flow from the turbocharger, while the GT86/BRZ intake focuses on improving airflow into the engine.

This makes them complementary examples of MST's approach to performance engineering:

More efficient airflow in + less restrictive airflow out = a more responsive performance system.

For enthusiasts building a modified vehicle, these types of airflow upgrades can also provide supporting hardware for additional engine and ECU modifications.
