Exhaust Clamp sizes

[Wobba]

Mine are shot to bits and a Magnex exhaust, graciously on loan from Summeh and Seanofnp (seperate bits!), will be put on soon as my exhaust is not healthy!

I want to fit a new clamp where the backbox and mid section meet, but is there any particular size I need? GSF ones are as follows:

28279 EXHAUST CLAMP 59-5 General Use 3.00 Add
28280 EXHAUST CLAMP 55-5 General Use 2.50 Add
28281 EXHAUST CLAMP-54.5 General Use 1.95 Add
28282 EXHAUST CLAMP-52.5 General Use 1.95 Add
28284 EXHAUST CLAMP-49.5 General Use 1.95 Add
28285 EXHAUST CLAMP-48.5 General Use 1.60 Add
28286 EXHAUST CLAMP-46.7 General Use 1.60 Add
28287 EXHAUST CLAMP-45.5 General Use 1.60 Add
28288 EXHAUST CLAMP 42-5 General Use 1.60 Add

Confused? Yes, I am! Hlep plx!

measure the pipe size and as long as you get one near the size of that it will tighten up
