Aussiespeed® took over the manufacturing of the Dutra Dual cast iron headers in march 2018 and from this date they will be manufactured in Australia and made available to customers worldwide.
It was through an article in Hotrod magazine where the Dutra Duals were used for testing and they worked hand in hand with the Aussiespeed® long and short intake manifolds.
NEW 2019 REAR AVAILABLE NOW NEW AS0567R-19 Supplied with Australian made manifold studs, brass nuts, steel flanges and flange gaskets. This total new design is made from its own new tooling, Cast from SG grade cast iron in Australia, CNC machined.
The intention of the new design is to fit with MOST factory and after market starter motors. As there are many models of starter motors we have tried to design a header to fit what we had available. If you find a combination of starter motor that it wont fit with we would appreciated any feedback.
You are buying 1 only front cast header that can be used as a replacement or with the popular cut and weld rear pipe conversion where a heat riser is still required for colder climates.
NOTE: These headers are CNC machined and should not require a lot of grinding to fit. Due to high demand there could be delays in delivery times. The new tooling we have invested in has better fitment at the cylinder head with both port alignment and flange profile.
