W375 “LS3 enhancement begins with the W375.”

Utilising a full stainless steel, stepped exhaust system, ceramic coated 4 into 1 long tube headers and high flow catalytic converters.

With this package we put the V8 growl back into the vehicle, with the note right there whenever you want it, not when the vehicles computer dictates.

We add an over the radiator cold air intake to gather greater volumes of airflow into the engine, resulting in greater efficiencies in power and economy. This is finished with all infill panels and shrouds keeping the with original equipment look of the vehicle.


ECU recalibration developed on a dyno takes full advantage of the increase in induction and exhaust performance, resulting in a very exciting driver’s vehicle that stands out from the crowd.

The package is supplied with rear deck lid badging, engine bay identification, certificate of Authenticity and Walkinshaw Performance’s warranty for complete peace of mind.

Please note, this package can also be supplied and fitted to vehicles with 6.0 litre engines such as VE and VF series 1, SS and SSV Commodores. The package for a VF Series 1 would be sold as a W310 package.
