@Claviger Rob,
Does the can come from @ozrider as well?
If not, where can I fond one like it in 2¼"?
 


Very very very similar to a sidewinder.

 

What way is are the flanges? How do you go from engine exhaust port shape to the round pipe?

That's usually the bit you have to kill for, most who have worked out a way to do it like to keep it to themselves. When Trevor made my CES system he asked me not to post photos of the flanges or how he made them.
 
I may have dyno numbers up on 30 March, depends how long they take to arrive and get back from coating.
