I'm going to be fitting a new stainless exhaust system in the next weeks.
Is it best to use stainless studs or bolts, cap heads as replacements?

Personally I have stainless studs and nuts with just flat washers , never come undone, if you use bolts you are turning at torque the bolt against the aluminium thread so more chance to damage it.

really depends if your exhaust has easy in line access to each stud, if not you may have to use some bolts.

My studs are actually grub screws so they come with a handy internal hex to remove and insert them

Like the grub screw idea, I'll see what I can get

And copper plated, brass nuts will look spangly too. Go on, you know you're van deserves the best

Steel studs x 6 with proper brass exhaust nuts, two of which can be external dia 1mm less than the other standard four, as it makes access to tightening those two up easier, what with the two tight J tubes. The last two fixings usually use bolts, again standard steel ones.
Each two years, during your major service, just wind them out and replace with new, easy job and cheap too.
If I did mine again I'd use steel studs, brass nuts but then stainless steel bolts for last two..
Just my tuppence...

Itchy's point about tightening bolts up into alloy heads is valid - I'd avoid it personally especially as the studs method can't be improved upon IMHO.

Stainless grubs or studs it is then , but gonna make sure I have bolts , nuts , cap heads at hand just in case . Ps is it M10

All M8, thread goes in about 20mm, depth of hole is about 25mm

I was mentioning, on the other current exhaust thread, how much I hate those 2 nuts you cannot remove without undoing the rest of the exhaust first

8mm SS Grub screws HERE

I am guessing these are suitable nuts -> Ebay link?

Oh and just to complete a shopping list, here are some 8mm SS washers -> another Ebay link

Those grub screws look uncannily like multi core cable

Ah, I was wondering who would be the first to spot that


Fixed the link now

Multicore cable now ordered , gotta say it will be easy to tie the exhaust on instead of using silly nuts and bolts
Ghost you need to patent this new method
