It won't gall as stainless can in any application, but the factory hardware definitely corrodes. I have worked on a lot of exhausts, and many are so corroded the bolts will break or have to be cut off due to the corrosion.
Stainless will work fine for the exhaust, but as Bob noted, use some anti-seize on the threads.

Incidentally all of the oem exhaust hardware is hardened, something that can't be done w/ ss.
It's your car....

And I thought all along that the nice Aeroquip (UK) clamps on our exhaust system were stainless.

I don't think the OEM bolts are ss, somebody correct me if I'm wrong. Nothing wrong with just picking up some 5/16" bolts from Home Depot and using some anti-seize. These are just exhaust tip bolts, guys. Save your money for something useful.

As I said I could car less what you do w/ your car. But at least be aware of the issues. If saving a few pennies is that important by all means scrooge away.

I think that was directed at me Andreas, but don't know why. I never indicated I was trying to save money on the bolts, just trying to find out what they were and where to get them other than the dealer. And happy holidays to you, too, Bill.

The oem hardware is remarkably well designed and implemented.

Im with bill on this one... They are stronger and harder than any SS I have seen. If SS would do the trick I'm sure Porsche would have gone that route rather than whatever special alloy they used.
When I got my car it had some cobbled together supertrapp exhaust. I had to replace the whole thing. I got all the nuts and bolts from DC Automotive for like $20. Threw them in the tumbler for an hour and they look/work like new.
Just my 2 cents...

I suspect Porsche didn't use SS because it can weld itself to itself... using SS nuts and bolts requires another step to maintain them. They would have to train Porsche Techs to use anti seize on exhaust clamp bolts. If the Techs did not use it they would quickly have many broken bolts on their hands and increased cost.
The bolts don't need to be hardened for this application.
Cost isn't really a factor either since neither are terribly expensive.
Buy the bolt that floats your boat
Much ado about bolts, eh?
