Torque Freaks or Ground Zero?

Yeah, Brian and his dad (Owners) are great guys. They'll treat you right.
I'll have to ask them what they thought of your system. I'm thinking of putting a new exhaust on mine.
Damn... My rattle has returned. The only thing I can think of is that possibly one of my test pipes flanges is set at the wrong angle. It was off by at least a half inch when I did the original install. I'm guessing that possibly that (along with the torque from the engine) is causing stress on the y-pipes and causing leaks/rattles.
I was hoping that the new exhaust would fix the problem. Hopefully the new y-pipe isn't permanently messed up.
