Pack of 4 Exhaust Mounting Rubber Mini Bobbin 5/16 UNF Silencer Holder

Product Information

You can actually tune the stiffness of it all my tightening the nyloc nut to adjust the compression of the bushes.

The leaders of the local classic club happened to have both of the subframe mounts laying around so he let me have them. Think I've replaced one in 15yrs since build - lots of use in all weather, and lives outside most of the time. So far I'm quite happy with the way this has worked out and a lot less worried than I was about using a single mounting point for the silencer. Now not all exhaust have the same mountings and hangers but this will give you an idea of what a good setup should look like! I was very careful to realign, slot, file, bend, adjust all my mounts to take and stress out of the bobbins as far as possible - ie it looks when installed, nice and straight, not angled between top and bottom, not in shear.And as you point out, most exhaust systems are suspended on rubber, but the original Mini bobbin I believe was intended to suspend the exhaust in tension rather than to be used under the exhaust in compression as on our cars, and with nasty shear and torsional loads if the exhaust and chassis brackets are even slightly misaligned or out of parallel.

The only concern I have is the possibility of the nyloc nut walking off as you can't clamp it down hard, but think this is extremely unlikely. My arches were from Huddersfield too, I got the outer lip trim but nothing for sealing the join between body and arch. The engine mounts are very rigid and there's enough length of pipe and available flex between the engine and rear mount that most modes can be discounted I would suggest.Please remember to add the forward-slash and not to put in any spaces in between the letters and numbers.

I'm sure it will provide sufficient vibration isolation and flexibility to allow the exhaust to move as required in use, but I will keep an eye on it to make sure it is holding up. Go to a motor factors like Halfords in the UK (or something similar where you are) and they should be able to supply you with some Mini (old classic Mini) exhaust rubber mounts, cheap as chips and similar to Norton stuff apart from a radiused centre. In reality I don't think it would make much difference as if you look at the pictures both the exhaust and chassis brackets are as wide as the washers. Assuming it's an RC40 (I wouldn't know, it looks like it could be though) would this kit contain all the bits I'd need? My initial concern about not using the washers was that the load would not be even across the rubber and the edges of the brackets might just bite in.

I don't know how but I took a knock to my rear exhaust mount pushing it almost parallel with the ground and pretty much folding the bobbin at right angles. What has always concerned me though was the fact that the while system was supported by a Mini exhaust bobbin which, if it failed, could allow the whole system to drop. I could have it modified to weld one on I guess but it would have been a little messy as that bolt hole in the chassis for the centre mount is right where my silencer clamp and lambda boss are.
