Questions about exhaust studs

[mustangflyr]

One more question: what exact product(s) am i looking for when I go to get "Anti-Seize" compund for the studs?

Be sure to use a copper based anti-seize compound not lead based on stainless steel.

Why is the copper compound better?

[dirtjones]

where can I get the exhaust studs? No one seems to know what I'm talking about?

[chuck hahn]

go to any bolt or fastener supply and ask for 2 inch stainless steel set screws..take a bolt with you so they can match the thread. Install the set screws with an allen wrnech and thats about it.

Why is the copper compound better?

because it stops a chemical reaction between the stainless and the aluminium, which can cause them to seize together

Good info..

It is called here electrolysis.
Principle of a battery is 2 dissimilar metals and an acid, creates electrolysis.
Aluminium and SS hate each other and together with contaminated water/road grime a receipy for corrossion and aluminium/SS thread corrosion

the whole idea of studding the engine is so you will NEVER EVER IN A MILLION YEARS have to take a bolt out to remove the exhaust. Who cares if it corrodes in there?? That will just keep them good and tight and thats that!! I did mine so i would never have to feel like i was crapping razor blades and praying everytime i had to take a bolt out!!!

I have the Napa Kit. $13 for 10 studs with nuts. They are a little on the short side for my Yoshi header though.... could do with another 10mm - 15mm length on them.

I got it on but it's a bit difficult getting the nuts started. I'm trying to find something longer... not located a metric 8mm x 1.25 in a longer size as yet.

Can someone explain what the kit is about? I don't have any bolts and need to replace them all. The stud kit sounds nice, if someone has a link or more information on them that would be cool. Also, if you know the replacement size for the stainless steel bolts I could use that also. Thanks.

Napa has only one 8mm stud kit. 10 of them in a clear pack, you'll find them.

If you get stainless bolts instead you want 45-50mm.

problem with your theory is when the nut and stud corrodes and snaps off and then you cant remove the rest of the stud because it has corroded into the head. 2 bolts per cylinder. removed and lubricated regularly will last longer than the bike will.
a stripped stud seized in the head is an expensive repair

In my full-time job, I deal all the time with fasteners that have been exposed to extreme temperatures.

Whether bolts, studs, nuts, whatever - if it's a threaded fastener exposed to heat and/or the elements: anti-sieze, anti-sieze, anti-sieze. You can use the nickel-based types for similar metals (steel-steel or stainless-stainless), but used the copper-based types when the materials are not the same. I never use the lead-based compounds.

Then, check them often. For the exhaust bolts OR studs, not a bad idea at all to add removal/anti-sieze/reinstall to a routine maintenance schedule.

Really, routinely checking any and all fasteners is a good idea.

Agemax..if the nuts rust or corrode on?? Thats the whole idea of STAINLESS STEEL studs..they dont rust or corrode!! Stainless steel washers and nuts too!! And for some god forsaken reason if they even seem a bit fussy just use a nut splitter and cut the friggin nut off!! Simple..effective ..and youll never have a snapped off exhaust stud ever again!!!
