Tip - hard to find exhaust tip bolts
My passenger side exhaust tip bolt started to loosen which caused vibration and noise. Unable to tighten so I tried to remove. All rusted so i had to cut off.
Tried to find a low shoulder M10 x 20mm carriage bolt but this seemed to be impossible. Porsche wanted to sell be the exhaust tip with a bolt as the bolt is not sold separately.
I found a very similar bolt here, 3/8 x 0.75" low shoulder.

Regular head carriage bolt can work but square shoulder is to long so several washers required as spacers in order create pre-load.

these bolts are also called "elevator bolts" - don't know why???, when sold at a local industrial hardware store.

Unfortunately, it is steel.
They also sell the Elevator Bolts:

I prefer stainless steel, but they didn't have metric. So the closest size is 3/8-16 X .75".
As far as the shoulder goes, if you want I would be happy to throw whatever you get in my lathe and trim it down to whatever size you want (no charge). Just private mail me.
A little story, my stock tips started rattling and coming apart on mine early in their life and I saw it an an excellent opportunity to upgrade to a new set of aftermarket stainless steel tips. They have held up far longer and better than the OEM tips and they look better, too.
