I use a flex socket and an extension.
I'm glad you are willing to go through so much trouble to get the torque right. Most exhaust bolts are grossly over torqued.
Terms such as Snug, not too tight, just a smidge, as tight as you can get it, until the wrench start to bend, etc. are terms that really hold no relevance to anyone, besides the person making that statement, when it comes to torque.
It's like a rich man saying to a poor man about the cost of something "It's not much at all". The cost of something probably quite relevant to the person stating it. A rich man may think $200 is not much and to a poor man it might mean $20.
"Snug" means something different to a person whose biceps are as large as my wrist.
