Exhaust Studs

[old son]

I want to replace my exhaust studs with stainless studs and nuts. Can anybody direct me on where to buy, size of thread , length etc.?

Pro bolt should do them, just done mine, pig of a job managed to get 5 out clean, two snapped halfway down, then flush so had to get them drilled out, I went oem from local yam dealer, there's a thread about how stainless can rot out the alloy threads, can't find it , try the search.

Yes, I've seen something about stainless and aluminium not playing nicely together.  That would explain why you don't see any references to others replacing OE studs with stainless alternates.  I'd stick OE studs and rely on cleaning and copper grease to keep them from rotting.

Thanks both. I also have an issue removing some Allen bolts from the front of the engine due to corrosion plus one of the bush inserts from the front engine mount is seized on the bolt. I think I will also require a replacement oil cooler and the metal piece that connects the cooler to the block, again due to corrosion.
