Looks good whats the part number and supplier for the bobbins, existing rubber bobbins just dont last...they have 5/16 threads and al components are mild stell and rust very quickly.
The 2 metal support brackets are available in stainless steel from librands
Where possible I fit stainless nuts bolts and washers on all exhaust components.
Are the U bolts / Exhaust clamps stainless and the nuts? All the underbody components really do get corrosion easily...
Bobbins part number GEX 7251 eBay
Exhaust U clamps are not stainless, only the washers, but maybe next time I’ll change them all to stainless. I did clean it all with ACF50 before refitting
