WTB pipe for custom intake 1.75"

Hi Y'all,
Where do you get stainless or aluminium pipe from in melbourne?
Need about 3-4 feet 1.75" ID to suit twin port intakes so I can connect it up to the SC12 supercharger

been there done that if you want any advice build it first out of plain steel pipe then when your happy have it done in stainless only tack it together that way you can pull it apart
good luck

why stainless?

i just used straight exhaust pipe and Richard at Vforce is gonna cermic coat it for me which looks just as good...ok not quite but still preddy and shiny
