Lookin at mine the 2 springs for the join at the bottom o the link pipe tea the headers are aboot are 110mmm approx when fitted.
The one at the top o the link pipe haudin the can on is aboot 95mm fitted.
Looking at them an if a remember right they are actually awe the same unfitted length. The ones at the lower join are definitely mair stretched look which wid back tha up.
Also think they were the same size length as the originals ah had on wi the Akras when bike wiz fire new.
Correct me if a speakin pish tho...
