14 ft lbs. there is a great install thread called cobra swepts install by Krazzy Mike.

 

Here you go...

I wouldn't fret the torque too much I was thinking about this as well when I did my install and didn't even end up using a torque wrench. Just do not over tighten because you can actually turn the bolt itself too far into the engine block and break it. But you would have to go waaaay too far for that just be careful and you will love the result I know I did. Also replacing the gaskets is highly recommended. Some guys say you don't have to but I did and always have on other bikes with great results. Good luck!

 

IMO new gaskets are cheap insurance.

 

Sorry for bringing this thread back to life, but does anyone know the size/part number for the bottom bolt on the top exhaust pipe? Mine may, or may not, have snapped off today.

Thanks in advance!
