Hi All,
It looks like the Aus A10 pipe is $Aud 374 which is about £220
if I 'm reading it correctly
I had to rework the Armours SS siamese pipes quite a bit to get the result I wanted
The biggest issue is getting the lefthand pipe to be a good fit into the head, as the bend is very tight
I used an industrial pipe expander to get the end back to size, but had to grind away a chunk of the cooling ring to get it to sit against the head
The Armours pipe 2 into 1 joining piece thats welded into the RH pipe is made from a straight piece, not curved like the original
You can see the original shape here,
