I’m in need of replacing my center muffler..I’ve had it of from the rear triangular 3 bolt joint to do rear suspension....however the 2 front nuts( engine end) tightened my sphincter so much I left them alone......anyone know if there all the same size( and what size?}...are they the same size / thread as manifold, turbo to man and turbo to down pipe?..............Im gong to slice them off rather than snap a stud....I’m fairly certain I have manifold bolts around and I’m guessing that a lock washer and bolt would also suit.?
Not in a position to source bolts after I’ve started...30 km trip
Cheers mark

It just so happens I've got the muffler off my 2012 tdci at the moment.
2-bolt (engine side) studs of the center muffler are M10 x 1.5

Cut studs, drill, and just use ordinary bolts if you have to. Nylocs will melt, just standard hi tensile steel will be fine.

Is “Center” a brand name or do you mean centre.

You should consider using your surplus of brain cells to contribute something useful instead of picking out spelling mistakes. A person of your incredible mental fortitude would surely be able to understand what was meant.

Jeez, glad I didn’t mention the “of” off issue, Toxic”, or I might have gotten a real hammering.

Mine look to be a pressed in dome head stud thing.....luckily there on the muffler side ,so it’s slice the bolts off

You might be surprised if you make a helical slice through the nut as best you can, and then give it a good whack with a cold chisel- sometimes this will split the nut enough to get it off. Of course, only applicable if you want to save the stud.
