I was thinking about changing the engine pipe on my vehicle and had thoughts about the hardware for reassembly.
Brass nuts was always the way to go but I thought about stainless? Any opinions?

Chevrolet used steel nuts, ........ they will last for 70 years on a restored car.

Gene
Is there any advantage to using brass or stainless steel when it comes time to remove them in the future?
Or does dissimilar metal corrosion come into play and make it worse?
I used steel and an anti seize compound on my truck and I'm just wondering what I'm in for in the future.

stainless on steel would be more prone to galling
on my 29 & 30 they are steel studs, brass nuts. works fine together
steel on steel or stainless on stainless also works

I have not had a problem using brass or stainless nuts on exhaust but steel nuts often rust in the threads and dont undo easily.

Just don't use a stainless nut on a stainless thread. You'll never get that back apart. Stainless on regular steel is fine.

Another trick I've used in exhaust systems is to coat nuts and exposed threads with RTV (silicone). When you need to remove the nut, just peel off the RTV. The nut and threads will be rust free and come right off.
