Exactly. You can tighten the axle nut to spec and it will still slip if you don't snug the adjusters counter-clockwise. Been there, done that.

I prefer not to remove the exhausts just to keep it simple. However, it's not so difficult, loosen the clamp (6mm hex key), remove the rear foot rest nut (12mm spanner), remove the foot peg while supporting the exhaust and ease it off the pipe, rest on an old folded bath towel to protect the chrome finish.

Before re-fitting clean off the old sealant and re-apply a new bead of clear RTV sealant, slip the exhaust on the pipe, loosely fit the rear peg, tighten the clamp, tighten the rear peg, wipe off any excess sealant and you're done.

Although you may find you can get by without the RTV sealant, I had the exhaust off for a new tyre in September and refitted it just as it came off and it resealed fine.

I never put sealant on my exhaust, and never have a problem,in fact there wasnt any on from new.

That is why so many tire shops had to replace rotors on MK1 Toyota MR-2's. Over ~80 ft-lbs and often the rotors would warp... It is a range for a reason, but it isn't always a critical one.

I generally don't use my torque wrench (but I am pretty well calibrated) but for certain jobs, it is a very necessary item to do correctly.

Oh, and I always torqued when I worked at Tire Station (now Firestone)...

I used to work in a service / repair garage and had to torque everything, especially wheel nuts.
I believe garages in the UK are more or less obliged to torque wheel nuts after complaints of over tightening with air tools and owners not being able to remove them in the event of a puncture. I've also heard cases of them shearing after hitting pot holes.
Manufacturers use torque settings for good reason.

I dont think anyone is arguing the merits of a torque wrench and would agree they are essential in many cases. we can all cite cases of over tightened wheel nuts and even a few undertightened wheel nuts.
however I dont think it is relevant in what the OP originally enquired, unless he is completely inexperienced in tightening a nut
