Bought a new RC40 system with the mounting kit The holes in the square centre block are no where near the threaded inserts in the sub frame - at least the diameter of a hole out - anyone else find this? The rear bracket for the cotton reels would line up but wrong place

exhaust mounts are always a pain in the arse - the design of the standard bits are just plain dumb - the mounts are held in shear instead of compression, so they're designed to fail I made a 'normal' one - wire brushed the rubber off a broken front one and welded on a rod, and welded a rod to the exhaust pipe there's a cotton reel at the back as well, when it fails I'll do something smarter with it too

Dave no worries...  makes it really really easy to hang the exhaust as well - you just pop it on, line up the extractors at the front and then do the cotton reel at the back - no shoving backwards and forwards, because it's nice and rubberysimon k wrote: I made a 'normal' one - wire brushed the rubber off a broken front one and welded on a rod, and welded a rod to the exhaust pipe
bit more detail on this - since the metal for the original rubber is quite thin and will bend easily, I actually welded a ~3mm plate to the back (between the 'ears') and drilled through it, the rod goes through the hole and is welded from the back the local exhaust wholesaler had a pallet load of those rubbers that they'd bought in for a customer, but had been stiffed and left with. I bought a box of 6 of them for $5, most suitable rubber I could find, and he wouldn't let me have just 1! |

I had the cotton reels on mine and after a while they just riped off, not enough movement in them to deal with the ride of a mini IMO. I have since fitted 2 rubber brackets like simon has. It's so much better and combined with a flexible exhaust joint near the extractors the system can be hit, dragged over and caught on a hole lot of things and the mounts just absorb it all  .
