Exhaust Leaks at X-Pipe to Cat Back Connection

I fired up the new 331 in the Coupe the other day and after letting it run for a bit I noticed that both connections between the X-Pipe and the Cat Back were leaking.  After I shut the motor off and things cooled down a couple of drip of water even dripped from these locations.  I still had the car up on jack stands so I took the X-Pipe back out.  The ball like connections on the X-Pipe were somewhat rough so I smoothed them out with some emery cloth.  I crawled back under the car and took a small flashlight to see what was going on.  The cup connection on the Cat Back were rough and just laden with carbon build up.  I jacked around with some emery cloth on those and soon realized it was getting no where fast.  The solution was pretty simple so I thought I would share it with you guys.  I took a cup brush that would work with my DeWalt 14.4 cordless drill and shined them up.  I chose a brush that was a little larger than the ID of the pipe so it would really clean up the ID of the pipe as well as get the lip of the cone connect clean.  If you angle the wire wheel at about a 30 degree angle and push it will cinch down and literally go into the flare and really clean it out.  Worked them over for a couple minutes each and got all the carbon build up out of the connection.  Went back after it with the emery cloth and got all the rough spots out.

Took a couple of hours but the exhaust is sealed up now and no leaks.  I wish I would have thought to take pictures but I spaced it.  I did however want to post up the wire wheel I am talking about so it would make more sense:

Methinks a dose of sarcasm cures all ills?

I was busting your balls about not carrying a dictionary with you or using word check and the fact that your post count is rising from 2-4 word posts...basically post whoring it up.
