I've lost many muffuler halves over the years.
The problem is..i can't get a decent torque from a miniture screwdriver( front) so i can tighten the rear nut good.

Luckily I've been able to get lock nuts with inserted star washers on them, this way it'll bite into the muffuler a bit.
I still double up on the nuts.

I've put JB weld, CA, expoxy on the threads behind the nuts to prevent the nuts from spining out.

The manufacture can resolve it easily by drilling a little hole into the bolt. This way you can loop a little
wire through to prevent the nuts from ever spining completely loose from the bolt.

It's the samething that's keeping the front wheels for your car from flying away.lol
You can turn that nut by hand even
Your lives are dependent on a little pin.lmao

If they can drill little air breed holes and other smaller holes, they can do this , if they wish to.

But they're arnt going to do that... becuase someone invested a lot of stocks on replacement muffulers parts.
