Guide to choosing/fitting exhausts
 

Can someone please tell me what I need to ensure that the Exhaust Can I buy off ebay will fit a pointy.

What diameter can should I look for, does the link pipe fit inside or outside the can, and inside or outside the downpipe?

Why are cans not interchangeable between curvy's and pointies?

there is a high level link pipe the seller says fits curvys & pointies - is this possible?
