What's the difference between headers and extractors?
In Australia the terms are used interchangeably. Both describe a tubular exhaust manifold replacement designed to improve exhaust flow over the stock cast manifold.
Do headers alone add much power?
Headers on their own give a modest gain, but paired with a matching cat-back exhaust and, where relevant, a professional tune, the gains compound significantly.
Are headers legal in Australia?
Yes, provided the catalytic converter is retained where the vehicle was originally fitted with one, and the vehicle still meets ADR noise and emissions requirements.
Which header brand should I choose?
Pacemaker, Advance, Hurricane and Genie each build model-specific ranges, so check compatibility for your exact engine and series before choosing between them.
