Maximise the power of your D-Teq 2.5. Deep, refined tone. Built for the long haul.
⚠️ Fitment Verification RequiredBefore ordering, please confirm that your 2.5 Isuzu D-Teq has the
same turbo flange design as shown in the image below — any variation in flange type will prevent proper installation.
Due to OEM differences, fitment may vary between models. In some vehicles, catalytic converters cannot be removed (cat-back system only).
🔧 Why Upgrade to a DeGraaf Exhaust?
Maximise the power and efficiency of your engine with the DeGraaf Performance Exhaust System — specifically engineered for the Isuzu D-Teq 2.5L (KB & D-MAX). 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 than factory systems — it improves throttle response, minimises turbo lag, and significantly lowers Exhaust Gas Temperatures (EGTs). This is a critical upgrade for protecting your engine during heavy-duty towing and off-road use. Experience the signature DeGraaf Growl: a deep, refined acoustic profile without intrusive cabin drone.
