i have NO idea where the install torque is for the STUDS.....but for the NUTS...it is 28.9ft-lbs FOR THE TURBO ENGINE
STUDS are installed at the factory and usually not removed...if they DO turn into bolts, re-installing them from the same hole they came out of is critical!!!!!
Torque values in the FSM are for NEW hardware and I have found that using torque values from the FSM on these exhaust parts and used hardware results in leaks and undertorqued fasteners.
I usually increase torque by 10-15% if using used hardware with good results.
ALSO....it is important to snug up these parts like wheel studs are tightened and in steps....I usually get everything(exhaust components) EVENLY tight to 22-23ft-lbs and let it sit for 10 minutes and then final torque.
RE-torquing after seveal heat cycles is also a good idea.
the highest toeque value per the fsm for this section is 28.9ft-lbs....which is pretty low for fasteners of this size
