Anatomy of a Hayabusa exhaust system

[Camel]

Okay, started on the header jig tonight. Started with a few chunks of aluminium plate that I'd prepared earlier and attacked them with a 42mm hole saw....



Then drilled.....



Here they are propped in position. I still need to tap them to 8x1.25 so they clamp the pipe and can be secured to the base plate.



I still need to make clamps for each outlet from the cat and clamps to hold the headers firmly in position where they bolt to the head.



The objective is to be able to remove the cat shell without disturbing the mounting positions.
