Stainless steel exhaust studs

[Trstno1]

Does anyone know the size and pitch of the exhaust studs in our cars?

Also, does anyone know where to purchase the stainless steel studs, lock washers and nuts?

We make these studs. They are M7 hardened stainless steel and are virtually impervious to corrosion. DPI carry's them as well. They are not on our new website yet but pricing is the same as Josh's and they are also available as a complete kit with one piece exhaust manifold gaskets.

Would it be better to use brass nuts on those stainless studs?

[PJ Grady Inc.]

We have three options on that. If you go with stainless on stainless you must use a product called tefgel on the threads to avoid galvanic action from the heat.
We can supply brass nuts but they are not particularely strong and can strip if overtightened.
My first choice is copper coated steel locking flange nuts which we include in our premium kits with the one piece OEM manifold gaskets.

Hey Rob, how much is the premium kit?

Hi Rob,

I am planning to go with brass nuts. Should I be using lock washers on the manifold and the bolt-together sections of the (UK stainless) exhaust?

Thanks in advance!

Hey Rob, is the Permatex stuff ok to use with the stainless on stainless application? I'm not sure where to get tefgel.

I just remembered the O2 sensor will need replacement. Is there a cross reference part, or does everyone just grab one from a vendor?

Might as well get one from a vendor for what they cost
