Mitsubishi Downpipes – Catted & Decat Performance Exhaust Upgrades

Mitsubishi Downpipes – Unlock the True Potential of Your Engine

Mitsubishi performance downpipes are among the most effective upgrades for turbocharged petrol and diesel engines. Whether you drive an iconic Lancer Evolution, a sporty Lancer Ralliart, a practical Outlander, or an ASX, upgrading your restrictive OEM downpipe to a high-flow Mitsubishi downpipe delivers more power, improved throttle response and an aggressive exhaust tone.

Why Upgrade to Performance Mitsubishi Downpipes?

Stock Mitsubishi downpipes are designed with emissions compliance and noise reduction in mind, but they limit exhaust flow and turbocharger efficiency. Installing a performance Mitsubishi downpipe offers significant advantages:

• Increased horsepower & torque – improve exhaust flow for stronger acceleration.
• Faster turbo spool – reduce turbo lag and enjoy sharper throttle response.
• Enhanced exhaust tone – catted downpipes deliver a refined sporty note, while decat downpipes unleash a raw motorsport-inspired roar.
• Lower exhaust gas temperatures – enhance engine efficiency and durability under load.
• Perfect for ECU tuning – essential for Stage 1, Stage 2 and hybrid turbo builds.

Types of Mitsubishi Downpipes

We offer a full range of Mitsubishi downpipes to suit every driving style and tuning level:

Catted Mitsubishi Downpipes

Catted downpipes integrate a high-flow sports catalytic converter, balancing emissions compliance with improved performance. Ideal for daily-driven vehicles in regions with strict emissions testing.

Decat Mitsubishi Downpipes

Decat downpipes remove the catalytic converter entirely, maximizing exhaust flow and ultimate power gains. Perfect for off-road builds, track cars or regions without emissions restrictions.

Material Options: Stainless Steel & Titanium

The material of your Mitsubishi downpipe has a direct impact on performance and durability:

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

Mitsubishi Models Compatibility

Our performance Mitsubishi downpipes are designed to fit a wide range of models and engine configurations:

• Mitsubishi Lancer Evolution Downpipes – optimized for Evo VII, VIII, IX and Evo X turbocharged engines.
• Mitsubishi Lancer Ralliart Downpipes – designed for 4B11T turbocharged setups.
• Mitsubishi Outlander Downpipes – perfect for both petrol and diesel engines.
• Mitsubishi ASX Downpipes – improve flow for efficient, powerful performance.
• Mitsubishi Pajero & Pajero Sport Downpipes – engineered for diesel torque and heavy-duty off-road use.

Performance Gains with Mitsubishi Downpipes

Upgrading to a performance Mitsubishi downpipe provides immediate and measurable results:

• +20–35 HP with a downpipe upgrade alone.
• +40–70 HP when combined with Stage 2 ECU remapping.
• Higher torque output for better mid-range performance.
• Sharper throttle response and reduced turbo lag.

Choosing the Right Diameter

Selecting the correct diameter ensures maximum efficiency and power:

• 2.5-inch downpipes – best for Stage 1 builds and lightly tuned engines.
• 3-inch downpipes – ideal for Stage 2 upgrades, hybrid turbos and high-boost applications.
• 3.5-inch downpipes – recommended for extreme performance and motorsport builds.

All Mitsubishi downpipes are designed for direct bolt-on installation with OEM-style fittings, ensuring a seamless upgrade without cutting or welding.

Build Quality & Engineering

Our Mitsubishi performance downpipes are manufactured to motorsport-grade standards:

• Mandrel-bent tubing for unrestricted exhaust flow.
• Precision TIG welding guarantees strength and durability.
• OEM-style flanges for perfect fitment.
• Available in stainless steel or titanium finishes.

Perfect for Tuning & Motorsport

Mitsubishi downpipes are essential for enthusiasts looking to push their build’s limits:

• Support aggressive boost targets for Stage 2 and Stage 3 builds.
• Improve turbo efficiency and acceleration.
• Deliver a motorsport-inspired exhaust tone with decat options.
• Compatible with ECU remaps, upgraded intercoolers and hybrid turbos.

Daily Driving vs Track Builds

For street-driven cars, catted downpipes balance performance with emissions compliance. For track-dedicated builds, decat downpipes maximize exhaust flow, unleash raw performance and deliver an aggressive exhaust tone.

Conclusion

Upgrading to Mitsubishi performance downpipes is one of the most effective ways to boost power, improve turbo spool and enhance exhaust sound. Whether you choose catted downpipes for refined street performance or decat downpipes for uncompromised motorsport results, our range guarantees premium build quality, seamless fitment and proven performance gains.
