go back to whoever put on your "true duals" and tell them to fix it. Im sure they just didnt tighten it back up enough.

By the way, the header does not bolt to the cat-back, if your exhaust guy says so, then i's suggest getting another exhaust guy.

Also, next time you have technical question, you'll probably have more help in one of the tech forums and not the lounge.

hope this helps
