So my mechanic and i put my car up on the hoist to install a new exhaust and we discovered that where the Cats connect to the turbos the bolts are all rusted so bad there is barely anything there. Called the dealership parts department ands they do not sell just the studs to replace they want me to buy all new turbos ( of course why would I expect anything different) anyway does anyone know what the size and thread the studs are that go in there ? or maybe if there is some kind of part number

Thanks

Assume this is a 997.1?

I replaced the studs and nuts the last time I put on a new exhaust.. I'd be very surprised if any dealer had some on the shelf, however. In my experience these days is that dealers stock very little parts and get most stuff shipped from one of the parts warehouses in the CONUS. I get all my genuine Porsche stuff from Sonnen.

Stud part #:
900-081-059-01
Online description seems to imply it's a M8 X22

Nut part #:999-084-203-01

Auto parts store will have the same studs at a third of the price.

I'm surprised the new exhaust didn't come with them...

Their ability to handle high temps is more important. I had some made up for me when I resolved the rusted nut issue on my ex UK car.

Factory studs are just 12.9

You can get them from McMaster-Carr https://www.mcmaster.com/#catalog/124/2650/=1e8jp7l 50mm ones work well with stock and aftermarket exhausts that some times have thicker flanges that the stock studs wont work with.
