Where to find rear exhaust spring w/ bolt?
I've lost one of the 2 spring loaded bolts for the rear pipe and cant seem to find them online anywhere.
A search pulled up the replacement bolt via this thread: https://www.rx8club.com/showthread.p...ht=spring+bolt
But I need the spring as well. Any suggestions would be greatly appreciated.
Thanks,

the dealer unless someone has one lying around
Part # YJ15-40-582 , about $6 msrp
the bolt/stud is Part # B31R-40-584, about $12 msrp from the dealer
the nut that holds the bolt/stud to the flange is Part # 9991-61-000
the nut that tightens the spring to the flange is Part # 9994-01-003
.

OEM part measurements
Since this is still the first google result for "rx8 exhaust spring bolt" I figure it's worth bumping with this info:
I bought the Mazda OEM exhaust springs and studs with part numbers: YJ15-40-582A and B31R-40-584 respectively.
The stud is threaded M10-1.25 on both sides.
More interesting is the hex nut size on the stud.
13mm socket will fit it, but there is a lot of slop possibly because of the curved corners on the hex.
A 1/2 inch, deep socket, is a far superior fit (see picture).
Anyway, hope this helps somebody not pay ~$45 for the OEM parts like I did.
I will edit this post when I do the install later on this week with any problems I run into.
EDIT: Keeping with my promise: the installation went reasonably well. I used a Magnaflow 23909 for my new cat/silencer setup.
It's worth noting that the shorter threaded side of the spring bolt is intended to screw into the cat/silencer pipe. The 23909 is not threaded in these holes and the flange is thick enough that only ~2 threads end up protruding on the other side of the flange hole. I simply turned the bolt around and used the longer threaded side to secure it to the flange. Problem solved.
