Sealing up exhaust

Awhile ago I installed a Magnaflow catback with the matching offroad X pipe. It was good for awhile, but now it has developed a leak.

The leak is right where the x pipe connects to the catback. The other day I went under there and the nuts were a little loose. So, I tightened them up. It was good for about a day, then it was leaking again. I crawled under there and the nuts were loose AGAIN. Ok, so tighten them up some more.. The next day, the same thing happens; It's leaking again.

So, this time I put some loc-tite on the studs and tightened them up. While I was under there I noticed the metal ring on the X-pipe that holds the studs was bent??!!

After I tightened the nuts, they weren't actually looseing off, the metal ring on the X-Pipe was bending and taking the slack off the nuts. When I tightened the nuts, the ring would hold but I think after a heat cycle, it would fatigue and bend, taking the tension off the nuts and making a leak.


Is there any way to seal those connections up? I think the metal rings on the X-Pipe are trashed now that their bent.

I was thinking of something like this.. Just a little less broken and a little more shiny

Anyone know what this type of clamp is called?

Is muffler mender permanent? I'd like to be able to get it apart if I ever have to.

I was also thinking about using some super-high-temp RTV to hopefully seal it up. Will the high-temp stuff hold up to the heat?
