Hi all.. I am assembling an exhaust system and I have brackets that take a long AN3 bolt to tie them all together - i.e. not ball type.
I see some installations like this are just with the bolt, others seems to have the bolt threaded through a spring, and would appreciate some advice on whether to add springs or not?
Thanks
