Mazda Downpipes – Catted & Decat Performance Exhaust Upgrades

( number of products: 1 )

Upgrade your Mazda with premium performance downpipes. Choose between catted and decat options to boost power, improve turbo spool and achieve a sportier exhaust tone.

Mazda Downpipes – Unlock the Full Potential of Your Engine

Whether you own a performance-focused Mazda 3 MPS, a sporty Mazda 6 MPS, or a modern SUV like the Mazda CX-5 or CX-30, your Mazda’s turbocharged engines have far more potential than the stock exhaust system allows. Upgrading to a performance Mazda downpipe is one of the most effective modifications to unleash hidden horsepower, improve throttle response, and achieve a deeper, sportier exhaust tone.

Why Upgrade to a Performance Mazda Downpipe?

The factory-installed downpipe is designed to comply with emissions regulations and noise limits, which restricts airflow and tuning potential. Replacing it with a performance downpipe brings several key benefits:

  • +20–50 HP on turbocharged petrol and diesel engines.
  • +60–90 HP when paired with Stage 2 ECU tuning.
  • Faster turbo spool – reduced backpressure improves boost response.
  • Lower exhaust gas temperatures – better thermal efficiency under high-load conditions.
  • Enhanced exhaust tone – catted for a refined sporty note, decat for an aggressive motorsport roar.

Types of Mazda Downpipes

We provide a full range of Mazda downpipes designed for various tuning levels and driving needs:

Catted Mazda Downpipes

Catted downpipes feature a high-flow sports catalytic converter that improves exhaust flow while maintaining emissions compliance. Perfect for street-driven cars and regions with emissions testing.

Decat Mazda Downpipes

Decat downpipes remove the catalytic converter entirely, delivering maximum power and airflow. Ideal for track builds, dyno tuning, and unrestricted environments.

Material Options: Stainless Steel & Titanium

The material of your Mazda downpipe influences weight, heat resistance, and durability:

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

Mazda Models & Engine Compatibility

Our Mazda downpipes are engineered to fit a wide variety of turbocharged petrol and diesel engines:

  • Mazda 3 MPS Downpipes – optimized for the 2.3 DISI Turbo engine.
  • Mazda 6 MPS Downpipes – designed for 2.3 turbocharged setups with AWD performance.
  • Mazda CX-5 Downpipes – available for 2.5 Turbo petrol and 2.2 Skyactiv-D diesel engines.
  • Mazda CX-30 Downpipes – tailored for 2.5 Turbo and 1.5 / 2.0 Skyactiv-G engines.
  • Mazda 3 Skyactiv-G / Skyactiv-X Downpipes – designed for modern performance and efficiency-focused engines.
  • Mazda MX-5 ND Turbo Downpipes – optimized for turbocharged conversions and high-performance builds.

Performance Gains with Mazda Downpipes

Upgrading your OEM downpipe to a performance Mazda downpipe delivers significant improvements:

  • +20–50 HP with a standalone upgrade.
  • +60–90 HP when combined with Stage 2 ECU remapping.
  • Sharper throttle response and faster boost build-up.
  • Improved torque delivery and top-end performance.

Stage 1, Stage 2 & Hybrid Turbo Builds

The Mazda turbo platforms respond extremely well to tuning when paired with a performance downpipe:

  • Stage 1 – catted downpipe + ECU remap for safe, balanced performance gains.
  • Stage 2 – decat downpipe + upgraded intercooler + custom ECU mapping for maximum output.
  • Hybrid turbos – large-bore 3.0-inch downpipes built for extreme power and track-focused builds.

Choosing the Right Diameter

Choosing the correct pipe diameter is critical for optimizing power gains:

  • 2.5-inch downpipes – ideal for Stage 1 builds and mildly tuned setups.
  • 3.0-inch downpipes – recommended for Stage 2, hybrid turbo conversions, and high-boost builds.

All Mazda downpipes are designed for direct bolt-on installation with OEM-style flanges for seamless fitment.

Build Quality & Engineering

Our performance Mazda downpipes are manufactured to the highest standards:

  • Mandrel-bent tubing for unrestricted exhaust flow.
  • Precision TIG welding for superior durability.
  • OEM-style gaskets and fittings ensure easy installation.
  • Optional ceramic coatings improve thermal efficiency.

Tuning Potential

Pairing your Mazda downpipe with ECU tuning unleashes its full performance potential:

  • Substantial horsepower and torque improvements.
  • Optimized boost control and fueling strategies.
  • Customizable exhaust tone based on catted or decat configuration.
  • Essential for Stage 2 and Stage 3 builds.

Catted vs Decat – Which One Should You Choose?

The best choice depends on your goals and driving style:

  • Catted downpipes – ideal for road-legal builds with emissions compliance and refined sound.
  • Decat downpipes – best for track builds and high-performance setups demanding maximum flow.

Conclusion

Upgrading to a performance Mazda downpipe is one of the most effective modifications to increase power, enhance turbo efficiency, and improve exhaust sound. Whether you choose a catted downpipe for street usability or a decat downpipe for ultimate performance, our range guarantees premium quality, perfect fitment, and proven gains.
