Exhaust nuts recommendations

[ashfixit]

Prepping for my new prospeed cats to come in for my '94. I took a look at the exhaust nut/stud hardware, that has been on the car for 16 years.

I think the prospeed cats should ship with m10x1.25 studs.. confirmation ??

After a bath in pb and a conservative blast with an unlikely ujoint/impact wrench setup; was able to remove the stuck hardware. I don't want to return any of the nuts to the new cats's studs.

Do you guys have a preferred exhaust nut that handles the temperature , salt corrosion, vibration and fouling? Would going stainless be bad? What kind of antisieze, antifouling do you use?



I saw these as a possible candidate .. but they look like 'merely' grade 8 steel :http://www.summitracing.com/parts/STG-4930/

The hot setup is ss bolts and bronze nuts but in general exhaust hardware should be considered throw away. Install and if you need to remove expect to break or torch off.

I've used NeverSieze with bronze/brass nuts on the standard steel studs on my previous Corvettes. I never had a problem getting them off and re-using the nuts after 50k to 100k mi. No reason it shouldn't work as well on the NSX.

im looking to replace my exhaust nuts and bolts. Where can i get SS bolts and bronze nuts for my 2000?

I'm curious as well....for my NA1 exhaust....what size bolts/nuts(14mm I believe)?

Thanks,


ps- this would be great for future reference as well.
