BOLT STABLE HORSE DOOR NISSAN SISTER

Please does anyone know where one can buy exhaust bolts?
It's for my sister's Nissan Micra, K12, 1996, which needs the central pipe replacing.
This connects t the back box and the fronh second cat.
I've got the central pipe, but can't find new bolts anywhere!
The old ones have had to come off with a splitter and cutter, as is
usual with most exhausts, so where does one buy the bolts and nuts?
There's no U Bolts involved.
Hope you can point me in the right direction.
best wishes
John

Yoda channelling you are.
There is nothing exotic about exhaust bolts unless they have to go into captive nuts.
If they do take the bits to a hardware shop or a motor factors and tell them how long they need to be.
Otherwise use whatever nuts, bolts and washers you can find that will bring sufficient pressure to bear on the job in hand.
If none of this is possible cut lengths of wire coat hanger on similar then put them through the offending bits and wind the ends together to achieve the above.
It will get V hot so don't be tempted to use cable ties.
Impressed, she won't be

Many thanks indeed, that's a massive help-I wasn't sure if exhaust bolts were super strength or heat resistant etc.
My sister will insist on having this modern car rubbish....
Thank you again

The bolts used on turbos should probably be high grade material as they go through a greater temperature cycle - anything else on the exhaust system is not really important.
I once paid a small fortune for some turbo bolts (they were actually studs and nuts) from a main dealer. I had to swallow hard.
For exhaust joints anything goes - the muppets that did the front pipe on wife's car used M8 nuts and bolts to replace the previous M10's. If the 2 bolts had even been the same length it wouldn't have looked so bad! When the exhaust fell off 2 weeks later they just shrugged their shoulders as it was the rubbers that failed and there aren't any rubbers on the front pipe... The rest of the exhaust
was fine and is now wrecked

If you can - brass nuts on zinc plated bolts will make life easier next time you take it to bits. But don't do them up too tight - it's easy to strip the brass.
