Exhaust Headers

[robbo]

if you go for dome nuts, make sure that the thread on the stud does not contact with the dome inside when torqued up, easy to get this wrong as the gaskets will compress when the nuts are tihjtened and lead to the stud tightening against the dome inner, givine the feeling that its fitted correctly when it isnt. A simpler option is to use connector nuts so its not a problem how much thread is exposed https://www.screwfix.com/p/easyfix-a2-st...pack/4720g

I did consider the connector nuts at the time, but preferred the idea I went for in the end, in using a regular stainless nut to hold the header in place, with the dome nut covering the small amount of exposed thread
that remained with no fear of it bottoming out, purely acting to seal the end of the stud from the elements. Peace of mind more than anything else, as any job involving exhaust studs usually doesn’t go as well as expected..
