Aussiespeed® Extractors are just another product that wasn't available so we added them to the range.
The 1 5/8 mandrel bent pipe are not butt welded but formed through the flange and welded.
The shorty design will fit from FJ to VK Commodore body styles and have been designed for Holden 6 cylinder 173 /2850 and 202 / 3.3 engines with 12 port cylinder head.
These headers are made in Australia and have been designed for Aussiespeed® intake manifolds and supercharger manifolds.
The 3 into 1 pipes are fully welded with a 2 1/4 inch collector. The pipes are stress relieved after welding and machining and are painted in a high temp exhaust paint.
Packages also available that include manifold and extractors.
