Double nut. What a great idea.

 

No kidding. I double nut using acorn nuts; protects the exhaust stud and the exhaust nut can't come loose... actually looks nice too

 

Damn, you beat me to it..Sometime you just have to think small Grind a socket down a bit as well for extra easy access. Not too much or the socket will split. That is a tight place. 1/4 drive and a swivel helps a lot. that and making sure your properly on the nut. Any half assed fit up is bound to slip and strip the nuts.
