Aye Rufus,
Landed safe then and the beasts put out to winter pasture?
The link below is for the Sammy Miller exhaust system for the TL 125, so maybe a tad pricey for what you are looking for, but Feked might be able to give you dimensions to offer up to the CG?
Link:
SM-complete-exhaust-system-tl125-and-sl125-modelsThere also apperars to be a difference between the electric start (ES) CG125 and kickstart exhaust pipes, with some of the later models having a length of pipe between the collar and head, rather than the collar fitting flush with the end of the pipe. Have a wee looksee on a search site 'images'.
Cheers, Bill
