A lot of people are saying they can't turn the nuts that are at the flange when they try to remove the stock mufflers. This nut is welded to the flange, you need to turn the bolt. No wrench is needed to hold the nut. If you round off the bolt head or can't turn it then you could cut the bolt head.

 

You are right,but I think that over the years with rust build up some people can't tell.

 

Too bad I didn't know about this last year when I took out the stock ones, I thought I was just a weakling w/ a wrench
