When it comes to modified cars a lots of people like to have a go at making there own custom components. Aussiespeed developed our own CNC bent 1 5/8 primary pipe Extractors a few years back and there has been the odd occasion where the pipes wouldnt fit with a certain body style due to where the engine had been positioned.
The head plates are exactly the same profile we use on our 1 5/8 mandrel bent pipe and with a bit of manipulation you can use the same pipe through flange process we use to make our pipes. Rather than a butt welded pipe to flange joint. These are laser cut from 10mm mild steel plate.Port height 39mm port width 38 mm
