NEW 2019 MODEL NOW AVAILABLE, MORE STARTER MOTOR CLEARANCE FOR BOTH USA and AUSTRALIAN SLANT 6 ENGINES
Dutra Dual cast iron headers were taken over in march 2018 from this date and will be manufactured in Australia and made available to customers worldwide by Aussiespeed.
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.
You are buying 1 only front CNC machined cast iron header that include a steel laser cut flange, flange gasket and flange studs nuts and washers.
These are CNC machined and should not require machining like the previous models. When used with some starter motors clearance is tight above the starter motor. Outlet is 2 inch.
The intention of the new design is to fit with MOST factory and after market starter motors. As there were 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.
NOTE: Headers pictured below in picture 3 are the older version of the Dutra Duels. The new Aussiespeed Dutra Dual headers are CNC machined and should not require a lot of grinding and should be a bolt straight on fit. PRICE IS IN USA dollars and includes shipping.
The pic above shows the latest model dutra dual headers with the new 2019 rear header design.
The CNC machined head flanges makes fitting easier.
