Damn, I was going to answer you then I got distracted by Garcou's Avatar......
What was the question again?

 

I have never used anti-seize on any exhaust nuts, bolts, whatever and I've probably built a few thousand engines in my time.

I quoteth from the official HD 2010 Service Manual for my 2010 Heritage:

1. Install upper nut and tighten finger tight
2. Install lower nut and tighten to 9-18 Inch Pounds
3. Tighten Upper Nut to 100-120 Inch Pounds
4. Tighten Lower Nut to 100-120 Inch Pounds

Thou shalt not under tighten, nor shouldest thou over-tighten the wholey Harley-Davidson Exhuast Nuts, nor shall ye apply any anti-seize or oil to the apointed fasteners . . . so sayeth the good book from Milwaukee of Wisconsin . . .

 

Thanks, LMAO.....

 

Anti-sieze and torque 1st nut lightly (60-80 in/lb) and then the other to spec (120 in/lb) & then finish 1st to 120 in/lb...repeat for other cyl. This allows the gasket to form properly. Also, remember to re-torque after 50-miles.
