Hi All
Centre box has had it; "Y" section, centre box and rear box purchased, also olive and fixings for "Y" to centre box joint. Need a fixing kit c/w clamps, can't find one on online, suggestions/recommendations please. Existing will probably be OK to reuse, but I would prefer to have all new.








 
Most of your clamps are standard exhaust clamps & available from Halfwits or any motor factor. Measure the o/d of the pipe & match to the right clamp - the measurements are stamped on the clamps but are unlikely to be visible on yours!
The ones with the longer legs (Pic 3 & possibly 5 unless there's another bolt in the middle of the clamp in which case a standard clamp will do with a hole drilled in it)are simply made by bending a bit of threaded stainless steel rod to replace the U section on a standard exhaust clamp. Heat to cherry red to aid bending.
Pic 4 has two clamps where one would probably suffice - or at least it does on mine:)
Pic 3. The pipe end to pipe end clamps are put on the pipe before the pipe ends are flared & the olive goes between the flared ends to seal. ETA these will already be fitted on your new system. I've replaced the triangular ones on my SS system which corroded through - so obviously mild steel - with ss ones that I cut & welded. . Just measure the bolt diameter & length & buy new ones.

Thanks for the detailed reply Ratae, I've had a measure and ordered up a variety of clamps (from Halfords), also some M8 studding to make bespoke clamps if needed.
There is a fixing kit available for the "Y" to middle section (including olive), bolts are FB108141L, olive is NTC1030.
