I have an aluminum Dr. CAI and it rubs agains the motor mount. I didn't notice it until recently and by then the motor mount had eaten a hole almost all the way through the piping. I didn't know what else to do so I put about 8 layers of heat resistant tape over the hole. Does anyone have any suggestions on what to do?

Also, the CAI bounces around because of the coupling and I can never get it tight enough to stop it from doing that. What could I do to solve that problem?

Rubbing-I'd say try adjusting the position, if not possible glue a junk of rubber in that spot..
bouncin around- find a means ie zip tie or similar to hold it still

The only part of my DR. CAI that touches is the top of my transmission. It barely touches it though, so you might want to play around with different angles to get it right where it should be. It took me a whole afternoon to get it assembled, but it's right where it's supposed to be.

I've tried adjusting the CAI to the position that your's is in, but it just won't go that way. I have mine pushed up into the coupling at the manifold pretty far because if I only push it in a little it bounces around really bad.
