Unleash the full capability of your YD25. Deep, refined tone. Built for the long haul.

🔧 Why Upgrade to a DeGraaf Exhaust?

Unleash the full capability of your YD25 engine with the DeGraaf Performance Exhaust System — precision-engineered for the Nissan Navara D40 2.5 Diesel. This premium 76mm stainless steel upgrade is designed to optimise exhaust flow, delivering tangible gains in kilowatt output and torque.

By reducing restrictive backpressure through CNC mandrel bending — offering up to 30% better flow — it improves throttle response, minimises turbo lag, and significantly lowers Exhaust Gas Temperatures (EGTs), which is essential for engine longevity during heavy-duty towing. Experience the iconic DeGraaf Growl: a deep and refined acoustic profile that highlights your vehicle's power without intrusive cabin drone.

⚡ Performance Benefits

• Increased Power (kW & Torque) — Optimised exhaust flow across the full rev range
• Improved Fuel Efficiency — Less restriction means your engine works smarter, not harder
• Sharper Throttle Response — Feel the difference from the moment you put your foot down
• Reduced Turbo Lag — Faster spool-up for a more responsive driving experience
