Kia Pregio 2.7L J2 Diesel Headers – Wildcat WILD291

Wildcat WILD291 exhaust headers (extractors) are designed for the Kia Pregio fitted with the 2.7L J2 diesel engine from 2002 to 2006.

Featuring an interference-style extractor design, WILD291 replaces the restrictive factory exhaust manifold arrangement with larger, smoother-flowing pipework. Improved exhaust flow helps the diesel engine expel exhaust gases more efficiently, reducing restriction and helping improve torque, throttle response and overall engine performance, particularly during acceleration and when working under load.

Why Good Headers & Exhaust Systems Matter

At 4,000 rpm, the 2.7L J2 diesel engine draws in approximately 5,400 litres of intake air per minute and expels around 16,200 litres of hot exhaust gas per minute at approximately 600°C. A well-designed header and exhaust system helps manage this high gas flow efficiently, reducing restriction and helping improve exhaust flow, torque, throttle response and engine performance, particularly when the vehicle is working under load.

Installation Tips

Apply penetrating lubricant such as WD-40 or similar to the manifold studs, nuts and exhaust fasteners before removal. Trial-fit the header and exhaust connection before cutting, adapting or fully tightening the system. Protect the painted surfaces during installation to minimise scratching or damage.

Warranty & Compliance

Wildcat headers are covered by the manufacturer's warranty subject to standard warranty terms and conditions.

Exhaust and emissions requirements vary between Australian states and territories. Installation must retain any emissions-control equipment required for the vehicle and comply with the regulations applicable in your state or territory.

FAQ

What Kia Pregio does WILD291 suit?
WILD291 is designed for the Kia Pregio fitted with the 2.7L J2 diesel engine from 2002 to 2006.

Does WILD291 connect directly to the existing exhaust?
The headers are designed for the applicable J2 engine, however the outlet needs to be adapted to the existing exhaust system. Professional exhaust installation is recommended.

What size are the header pipes?
WILD291 uses 1.50" (38.1mm) primary pipes, 1.75" (44.45mm) secondary pipes and a 2.00" (50.8mm) outlet.

Is a new manifold gasket required?
The original manifold gasket may be reused if it remains in good serviceable condition. We recommend inspecting the gasket during installation and replacing it if damaged or deteriorated.

Are these headers suitable for a working diesel van?
Yes. The extractor design is intended to reduce exhaust restriction and improve gas flow, which is particularly useful when the engine is operating under load.

Can I pick up from the store?
Yes. Pick up is available but must be pre-arranged before collection.

How much is freight?
Freight varies depending on your delivery location and where stock is available. Please contact us for freight charges before ordering. Where possible, we can arrange dispatch from the nearest available product location to help reduce freight costs and delivery times.
