nuts - i use brass/copper ones - gsf supply for 50p each.

studs are m8x28 i think.  Could try stainless ones?

problem is they are a very short stud, most are much longer. Not sure where to get one in that size.


the nuts look ok after a while.

doubt they're going to stay looking clean for very long no matter what material they are made of.

Studs I would get standard. The only thing I might be tempted to get different is stainless washers.

I paid £8 each for some VAG one's whe I was in a rush..! I feel aggrieved now.
I'd now buy the 50p ones and change them 16 times.

It`s worth replacing studs if there lookin a bit manky if you have the head off
or are fitting a zorst/gasket whatever.

I`d fit standard or good equivalent ones as they are tempered correctly.
They work harden over time with being heated up and cooled many times
Hence why they eventually snap.

Don`t use Stainless Threaded bar as stainless has a different expansion
rate to normal steel and pulls/bends/contorts more.
The studs they supply are used for a reason.

manifold studs - 50p each

down pipe studs - mucho moolah!
Title: Re: exhaust manifold studs and nuts?
Post by: lance on April 30, 2009, 02:08:41 PM
yea i remember pricing downpipe ones am sure they where £11 each!

Seriously, (although I now realise I meant the other end of that manifold, where it meets the downpipe, appologies) I have been looking at the recipt now in amazement .. The gasket was special too, and a lot more than the cheapo one that fits a GT i got by accident. I got the manifold studs off a scrap VW and new nuts. Just paid and accepted it's worth it...

Brass nuts are an essential. Stainless nuts or studs are often permanently attached once they have been hot a few times!

If you need studs, nuts or exhaust clamps these guys sell in bulk and are often cheaper than anyone else.
