Where to source exhaust collector springs?

[Andy135]

Anyone know where I can source a couple of these exhaust collector springs?

Of course, they're handily out of stock at Caterham but they surely must be found elsewhere too. All the searching I've done only comes up with springs made of of single wire with hooks at each end, rather than the 3-piece versions in the link above.

I'd ask Redline.

I've not seen the Caterham supplied one but it looks like the old Austin Rover type. Try this exhaust spring but do check it's the same

By finding and using the centre mount on my chassis, I no longer need any springs or bolted brackets between my primaries and collector

#3, that looks like the right sort of spring. I've also just spoken to Raceline and they have some in stock so I've put in an order with them.

Next question is how to fit the top one, as on my car at least, the old one is coil-bound yet does not have enough free play to slide over the hooks, so I can't see how to get it off other than by using a destructive method... which begs the question of how to get the new one on. Any tips from those who have done this before?

#5 Use a couple of cable ties to compress the spring (applies to removal and refitting).  If it still won't clear the hooks, you may have to bend one of them slightly.

I found the solution... used a screwdriver to prise open the top of the spring then wound the arms of the loop through the spring (think of threading a key on/off a key ring and you'll get the idea). A squirt of WD40 helped to make the spring easier to rotate. This reduced the number of coils separating the loops and extended the reach of the loops enough that I could slide one of them over the exhaust hook. Problem solved and I can re-use the spring.
