tunnel brace
Another suggestion for you to eliminate the vibrating issue is to loosen up the Y Pipe and readjust it so you have the clearance and then re-tighten it back up. What a lot of guys do is they just remove the braces and replace them with a DS loop. Below is a link to show you what I am talking about.

Well in that case just remove the factory tunnel brace. They're are many people that do this and it will eliminate your problem. If you have any other questions feel free to ask.
