So, the neighbor's college freshman son drives a 93 Grand. The exhaust corroded into bits behind the cat. No big deal, get a muffler and a new tailpipe.
Except....
He let one of his buddy's brothers work on it. Ohmygawd....... after looking it over this afternoon (he called me when the muffler came loose from the cat again,) I told him just don't introduce me to the bozo who did this.
He ended up with the wrong muffler. Inlet is too small, so it doesn't make a good seal with the cat. Outlet is too big (no, it's not installed backwards, it's just the wrong muffler,) so it has a crummy joint with the tailpipe. Both sides are double-clamped. The muffler outlet has been hacked to try and make the seal (it failed.) The tailpipe is between the swaybar and the axle, so the tailpipe just doesn't go high enough. As a result of that, the kid hacked off the tailpipe hanger and tied it up with quarter inch rope.
Some peope just shouldn't be allowed to have wrenches.
