Honda Downpipes – Catted & Decat Performance Exhaust Upgrades

Honda Downpipes – Unlock Your Engine’s True Potential

When it comes to maximizing performance, upgrading your Honda downpipe is one of the most effective modifications you can make. Whether you drive a Honda Civic Type R, Honda Accord, Honda S2000, or a turbocharged Honda CR-V, replacing the restrictive OEM downpipe allows your engine to breathe better, improves exhaust gas flow, and unlocks hidden horsepower.

Why Upgrade to a Performance Honda Downpipe?

The factory-installed downpipe is designed with emissions and noise restrictions in mind, which often limits your vehicle’s full performance potential. A performance Honda downpipe offers several key benefits:

• Increased horsepower & torque – reduced exhaust backpressure improves combustion efficiency.
• Faster turbo spool – optimized flow allows your turbo to build boost quicker.
• Improved exhaust sound – choose catted for a refined tone or decat for an aggressive motorsport roar.
• Lower exhaust gas temperatures – better heat management protects critical components.
• Perfect for ECU tuning – essential for Stage 1, Stage 2, and hybrid turbo setups.

Types of Honda Downpipes

We provide a wide range of Honda downpipes designed to suit different driving styles and tuning levels:

Catted Honda Downpipes

Catted downpipes feature a high-flow sports catalytic converter, offering a perfect balance between performance and emissions compliance. Ideal for daily drivers in regions with emissions testing.

Decat Honda Downpipes

Decat downpipes remove the catalytic converter entirely, maximizing exhaust flow for raw performance. Recommended for track builds and off-road applications where emissions are not regulated.

Material Options: Stainless Steel & Titanium

The material of your Honda downpipe impacts weight, durability, and thermal efficiency:

• Stainless steel downpipes – cost-effective, durable, and corrosion-resistant.
• Titanium downpipes – ultra-lightweight with superior heat resistance and a premium motorsport finish.

Honda Models Supported

Our selection covers a wide range of Honda models and engine configurations:

• Honda Civic Type R FK8 / FL5 Downpipes – optimized for K20C1 turbo engines.
• Honda Civic Si Downpipes – improve power and spool for turbocharged variants.
• Honda Accord 2.0T & 1.5T Downpipes – tailored for smooth performance gains.
• Honda CR-V Turbo Downpipes – enhanced flow for efficient low-end torque.
• Honda S2000 Downpipes – ideal for naturally aspirated tuning or turbo conversions.

Performance Gains with Honda Downpipes

Upgrading your OEM downpipe delivers instant performance improvements:

• +15–35 HP with a standalone downpipe upgrade.
• +40–70 HP when paired with Stage 2 ECU tuning.
• Enhanced throttle response and reduced turbo lag.
• Optimized torque curve for better drivability.

Choosing the Right Diameter

Selecting the correct downpipe diameter ensures maximum performance gains:

• 2.5-inch downpipes – recommended for Stage 1 setups and lightly tuned cars.
• 3-inch downpipes – ideal for Stage 2 builds, hybrid turbos, and high-boost applications.

All Honda downpipes are designed for direct bolt-on installation, eliminating the need for cutting or welding.

Build Quality & Engineering

Our performance Honda downpipes are crafted to meet motorsport-grade standards:

• Mandrel-bent tubing for smooth exhaust flow.
• Precision TIG welding for maximum strength and durability.
• OEM-style flanges and fittings for a perfect fit.
• Thermal coatings available for additional heat management.

Tuning Potential

A performance Honda downpipe paired with ECU remapping unlocks its full potential:

• Significant horsepower and torque improvements.
• Optimized turbo response and boost control.
• Customizable exhaust sound based on catted or decat setup.
• Essential for Stage 2 tuning and beyond.

Daily Driving vs Track Builds

Choosing the right Honda downpipe depends on how you use your car:

• Catted downpipes – perfect for daily driving, emissions compliance, and balanced performance.
• Decat downpipes – best for track builds, time-attack cars, and ultimate power gains.

Conclusion

Upgrading to a performance Honda downpipe is one of the best investments for extracting more power, improving exhaust tone, and optimizing turbo efficiency. Whether you choose a catted downpipe for road use or a decat downpipe for uncompromised performance, our selection guarantees precise fitment, premium materials, and proven results. Transform your Honda today and take your build to the next level.
