When replacing the exhaust, can you just tighten it down "until it's tight" without obviously going overboard, or should one really be using a torque wrench?
Some say no,I say yes.I do everything by the book, and rarely suffer break downs.To ensure there are no exhaust leaks you need to torque them down and possibly use new header gaskets.You will need to re-torque after a few rides.Also,antiseize on the bolt threads will give a more accurate torque setting and help the bolts come out later, if you need to remove the exhaust again.
def torque them to spec. don't take a chance on critical components
If you use antisieze on the fixings DO NOT use the manufactures torque figure. Figures quoted are for dry threads, if you lube them you reduce the friction between the male and female threads, but with the same torque applied they will stretch and weaken..........reduce the figure by about 75%

Really?At 15 foot pounds of torque?75% of 15 is what 5?Really?
Yeah, curious to hear a response on this. 15lbs is the lowest setting on my wrench...

33% of 15 is 5.
75% of 15 is 3/4 of 15 is 11.25

Once you get below about 10 or 15 foot pounds,it's more accurate to use an inch pound torque wrench.I borrow my friends and it has a big dial on it like a dial indicator.
Kinda like this one.

I got it backwards.
Whatever. I've got no anti-seize, but it may have been applied when I took it to the shop (seems like it was). Either way, 3.75 lbs difference? That's not a lot. Imma just go with stock/what Haynes is telling me (15lbs).
