Nissan GT-R R35 Downpipes – Catted & Decat Performance Exhaust Upgrades

Nissan GT-R R35 Downpipes – Unlock the Full Potential of the VR38DETT

Nissan GT-R R35 performance downpipes are one of the most effective exhaust upgrades for the legendary VR38DETT twin-turbo engine. Whether you drive a stock GT-R or a fully built Stage 3+ tuning setup, upgrading to a high-flow R35 downpipe unlocks horsepower, improves turbo efficiency and delivers a motorsport-grade exhaust tone.

Why Upgrade to Performance R35 Downpipes?

The factory R35 downpipes are designed to meet emissions and noise standards but severely restrict exhaust flow and turbo response. Upgrading to a performance R35 downpipe delivers:

• Significant horsepower & torque gains – improved exhaust flow boosts overall engine performance.
• Faster turbo spool – reduce lag and sharpen throttle response.
• Motorsport-inspired exhaust tone – catted downpipes give a deep, refined sound, while decat downpipes unleash an aggressive roar.
• Lower exhaust gas temperatures – optimized thermal efficiency protects the VR38DETT under heavy load.
• Perfect for ECU tuning – essential for Stage 1, Stage 2, Stage 3 and hybrid turbo builds.

Types of Nissan GT-R R35 Downpipes

Our R35 downpipes are designed for various tuning stages and driving needs:

Catted R35 Downpipes

Catted downpipes integrate a high-flow sports catalytic converter to balance emissions compliance with increased performance. Perfect for street-driven GT-Rs in regions requiring emissions testing.

Decat R35 Downpipes

Decat downpipes remove the catalytic converter entirely, maximizing exhaust flow and unlocking peak performance. Ideal for track-focused builds or locations without emissions restrictions.

Material Options: Stainless Steel & Titanium

The material of your Nissan R35 downpipe affects durability, weight and heat resistance:

• Stainless steel downpipes – durable, corrosion-resistant and cost-effective, perfect for daily-driven setups.
• Titanium downpipes – ultra-lightweight, motorsport-grade and excellent for extreme heat management.

Nissan GT-R R35 Engine Compatibility

Our performance Nissan GT-R R35 downpipes are engineered for the VR38DETT 3.8L twin-turbo engine and fit all trims:

• GT-R R35 Premium Downpipes – designed for factory configurations.
• GT-R R35 Nismo Downpipes – optimized for the ultimate factory performance variant.
• GT-R R35 Track Edition Downpipes – built for motorsport-focused setups.

Performance Gains with Nissan R35 Downpipes

Upgrading to a performance GT-R R35 downpipe yields measurable improvements:

• +30–60 HP from a downpipe upgrade alone.
• +70–120 HP when combined with Stage 2 ECU remapping and supporting mods.
• Improved torque delivery for stronger mid-range and top-end acceleration.
• Sharper throttle response and reduced turbo lag.

Choosing the Right Diameter

The correct downpipe diameter is crucial for optimizing performance:

• 3-inch downpipes – suitable for Stage 1 and Stage 2 builds.
• 3.5-inch downpipes – recommended for Stage 3 high-boost setups and hybrid turbos.
• 4-inch downpipes – best for full race-spec, big-turbo conversions.

All Nissan GT-R R35 downpipes are designed for direct bolt-on installation, ensuring seamless integration without cutting or welding.

Build Quality & Engineering

Our R35 performance downpipes are manufactured to motorsport-grade standards:

• Mandrel-bent tubing ensures smooth, unrestricted exhaust flow.
• Precision TIG welding guarantees strength and durability.
• OEM-style flanges ensure perfect fitment with stock or aftermarket exhaust systems.
• Available in premium stainless steel and ultra-light titanium.

Perfect for Tuning & Motorsport

Nissan GT-R R35 downpipes are essential for enthusiasts aiming to push their builds further:

• Support aggressive boost targets for Stage 2, Stage 3 and beyond.
• Enhance turbocharger efficiency and exhaust flow.
• Deliver a motorsport-inspired exhaust note with decat options.
• Fully compatible with ECU remaps, upgraded intercoolers and hybrid turbo conversions.

Daily Driving vs Track Builds

For street-driven GT-Rs, catted downpipes offer performance gains while retaining emissions compliance. For dedicated track cars, decat downpipes deliver maximum flow, peak power and a raw, motorsport sound.

Conclusion

Upgrading to Nissan GT-R R35 performance downpipes is one of the most effective modifications to unlock power, enhance turbo response and achieve a motorsport-grade exhaust tone. Whether you choose catted for refined street performance or decat for ultimate track dominance, our selection guarantees premium quality, seamless fitment and proven gains for every R35 build.
