Nissan 350Z Downpipes – Catted & Decat Performance Exhaust Upgrades

Nissan 350Z Downpipes – Unleash the Potential of Your VQ35 Engine

Nissan 350Z performance downpipes are one of the most effective exhaust upgrades for the legendary VQ35DE and VQ35HR engines. Whether you’re running a stock 350Z, a Stage 2 tuned setup or a full-blown track build, upgrading to a high-flow Nissan 350Z downpipe maximizes power, improves exhaust tone and enhances driving dynamics.

Why Upgrade to Performance Nissan 350Z Downpipes?

The factory downpipes on the Nissan 350Z are designed to meet emissions regulations and noise limits, but they restrict exhaust flow and reduce performance. Upgrading to a performance 350Z downpipe delivers:

• Increased horsepower & torque – better exhaust flow improves combustion and engine efficiency.
• Improved throttle response – faster power delivery across the rev range.
• Enhanced exhaust tone – catted downpipes provide a refined, sporty sound, while decat downpipes unleash an aggressive, motorsport-inspired roar.
• Lower exhaust gas temperatures – optimized thermal efficiency extends component life.
• Perfect for ECU tuning – ideal for Stage 1, Stage 2 and forced-induction builds.

Types of Nissan 350Z Downpipes

Our selection of Nissan 350Z downpipes suits all driving styles and performance goals:

Catted 350Z Downpipes

Catted downpipes integrate a high-flow catalytic converter that improves performance while maintaining emissions compliance. Ideal for street-driven 350Zs in regions with strict emissions testing.

Decat 350Z Downpipes

Decat downpipes eliminate the catalytic converter completely, maximizing exhaust flow and peak power output. Best suited for track-focused builds or areas without emissions restrictions.

Material Options: Stainless Steel & Titanium

Material choice affects performance, weight and durability:

• Stainless steel downpipes – durable, corrosion-resistant and cost-effective for daily-driven cars.
• Titanium downpipes – ultra-lightweight, heat-resistant and motorsport-grade engineering.

Nissan 350Z Engine Compatibility

Our performance Nissan 350Z downpipes are designed to fit all VQ35 engine variants and trims:

• 350Z VQ35DE Downpipes – optimized for early-generation engines (2003–2006).
• 350Z VQ35HR Downpipes – engineered for later-generation high-revving engines (2007–2009).
• 350Z Nismo Downpipes – designed for the high-performance Nismo edition.

Performance Gains with Nissan 350Z Downpipes

Installing a performance Nissan 350Z downpipe brings measurable improvements:

• +12–25 HP from a downpipe upgrade alone.
• +30–50 HP when combined with ECU tuning and supporting mods.
• Better torque delivery for stronger mid-range acceleration.
• Improved exhaust flow for a deeper, sportier tone.

Choosing the Right Diameter

Selecting the correct diameter is key to achieving your performance goals:

• 2.5-inch downpipes – ideal for lightly tuned Stage 1 builds.
• 3-inch downpipes – recommended for Stage 2 setups, turbo kits and high-rev applications.

All Nissan 350Z downpipes are designed for direct bolt-on installation, ensuring perfect fitment without cutting or welding.

Build Quality & Engineering

Our Nissan 350Z performance downpipes are crafted to motorsport standards:

• Mandrel-bent tubing ensures smooth, unrestricted exhaust flow.
• Precision TIG welding guarantees maximum strength and leak-free operation.
• OEM-style flanges ensure seamless integration with stock or aftermarket exhausts.
• Available in stainless steel or ultra-light titanium.

Perfect for Tuning & Motorsport

Nissan 350Z downpipes are essential for enthusiasts who want to extract maximum performance:

• Support aggressive boost targets for turbo or supercharged setups.
• Enhance turbocharger efficiency and throttle response.
• Deliver a motorsport-grade exhaust tone with decat configurations.
• Compatible with ECU remaps, upgraded intercoolers and full exhaust systems.

Daily Driving vs Track Builds

For everyday driving, catted downpipes provide an excellent balance between performance and emissions compliance. For track-focused 350Zs, decat downpipes offer maximum exhaust flow, top-end power and an aggressive sound profile.

Conclusion

Upgrading to Nissan 350Z performance downpipes is one of the most effective modifications to improve power, throttle response and exhaust tone. Whether you choose catted for a refined street setup or decat for ultimate motorsport gains, our selection guarantees premium quality, perfect fitment and proven results for every 350Z build.
