Mitsubishi Lancer Evo VIII Downpipes – Catted & Decat Performance Exhaust Upgrades

Mitsubishi Lancer Evo VIII Downpipes – Unleash the Full Potential of Your 4G63T

Mitsubishi Lancer Evo VIII performance downpipes are among the most effective exhaust upgrades for the legendary 4G63T turbocharged engine. Whether you’re running a lightly tuned Stage 1 setup or building a fully forged Stage 3 motorsport Evo 8, upgrading to a high-flow Evo VIII downpipe improves power, torque, turbo response and exhaust tone.

Why Upgrade to Performance Evo VIII Downpipes?

The factory downpipe on the Evo VIII is designed to prioritize emissions and noise regulations, limiting exhaust flow and turbocharger efficiency. Installing a performance Evo 8 downpipe delivers:

• Substantial horsepower & torque gains – free up exhaust flow for stronger mid-range and top-end performance.
• Faster turbo spool – reduce lag and achieve sharper throttle response.
• Enhanced exhaust note – catted downpipes provide a refined tone, while decat downpipes deliver a raw, motorsport-inspired roar.
• Lower exhaust gas temperatures – improve thermal efficiency and protect critical components.
• Perfect for ECU tuning – essential for Stage 1, Stage 2 and hybrid turbo builds.

Types of Mitsubishi Evo VIII Downpipes

Our range of Evo VIII downpipes covers every tuning style and application:

Catted Evo VIII Downpipes

Catted downpipes integrate a high-flow sports catalytic converter, balancing emissions compliance with strong performance gains. Ideal for street-driven cars in regions requiring emissions testing.

Decat Evo VIII Downpipes

Decat downpipes remove the catalytic converter entirely, maximizing flow and delivering ultimate performance. Best suited for track builds or areas without emissions restrictions.

Material Options: Stainless Steel & Titanium

The material of your Evo 8 downpipe affects weight, performance and durability:

• Stainless steel downpipes – durable, corrosion-resistant and cost-effective, suitable for most setups.
• Titanium downpipes – ultra-lightweight, superior heat management and motorsport-grade engineering.

Mitsubishi Evo VIII Engine Compatibility

Our performance Evo VIII downpipes are designed specifically for the 2.0L 4G63T turbo engine and compatible factory setups:

• Evo VIII GSR Downpipes – optimized for standard turbo configurations.
• Evo VIII RS Downpipes – lightweight, race-inspired options for track use.
• Evo VIII MR Downpipes – engineered for MR variants with unique exhaust layouts.

Performance Gains with Evo VIII Downpipes

Upgrading to a performance Evo VIII downpipe delivers instant, measurable benefits:

• +20–35 HP from the downpipe upgrade alone.
• +40–75 HP when combined with Stage 2 ECU remapping.
• Increased torque for stronger acceleration and mid-range punch.
• Sharper throttle response and reduced turbo lag.

Choosing the Right Diameter

Selecting the proper diameter is crucial for maximizing power gains:

• 2.75-inch downpipes – perfect for Stage 1 setups and mild builds.
• 3-inch downpipes – ideal for Stage 2 and hybrid turbo upgrades.
• 3.5-inch downpipes – recommended for extreme Stage 3 motorsport applications.

All our Mitsubishi Evo VIII downpipes are designed for direct bolt-on installation, ensuring OEM-like fitment without cutting or welding.

Build Quality & Engineering

Our Evo VIII performance downpipes are built to motorsport-grade standards:

• Mandrel-bent tubing for smooth, unrestricted exhaust flow.
• Precision TIG welding ensures strength and long-lasting durability.
• OEM-style flanges for seamless integration.
• Available in stainless steel and lightweight titanium.

Perfect for Tuning & Motorsport

Mitsubishi Evo VIII downpipes are an essential upgrade for enthusiasts aiming for maximum performance:

• Enable aggressive boost targets for Stage 2 and Stage 3 builds.
• Optimize turbocharger efficiency and heat management.
• Deliver a motorsport-grade exhaust tone with decat options.
• Compatible with ECU remaps, upgraded intercoolers and hybrid turbos.

Daily Driving vs Track Builds

For street-driven Evos, catted downpipes provide the best balance between emissions compliance and performance. For track or high-boost builds, decat downpipes maximize flow, top-end power and exhaust aggressiveness.

Conclusion

Upgrading to Mitsubishi Lancer Evo VIII performance downpipes is one of the most effective ways to enhance power, turbo response and exhaust tone. Whether you choose catted for refined road performance or decat for ultimate motorsport gains, our selection guarantees premium build quality, seamless fitment and proven results for every Evo VIII setup.
