Our Monaro headers are manufactured in the UK to wortec specifications.  They have been specifically designed by wortec to increase torque across the rev range and allow the engine to breath. 

The design brief was to provide a set of headers that not only provided performance but a were a good fit and produced a great sound.  

They are manufactured from 304 grade stainless steel to withstand all the ravages of the British climate.  When combined with our performance cat’s they provide a great upgrade to any Monaro.
