Racing Performance Works Race Header Systems are designed as the complete "Direct Bolt on Package" meaning no further components or parts are required. You purchase this product and simply bolt onto your vehicle, no welding or modifying is required.

The package includes the RPW 4-1 Racing Header and Flex Pipe Assembly. Cat converter is required to be purchased separately, either as a bolt on kit manufactured by RPW, or utilising a local universal supplier which will require welding and adapting due to the factory cat converter being integral to the factory flex pipe.

All O2 Sensor fittings are fitted, where vehicles run multiple O2 Sensor Fittings, all the location points are available. On models where cat converters are supplied, O2 sensor fittings are also mounted after the cat converter to avoid CEL / Check engine Light issues.
