ECS Valved Exhaust lateral movement issue

[enj826]

I'm currently in the process of installing an ECS Valved Exhaust for my S5. One issue I've noticed when finishing up the installation is that there is a ton of lateral movement due to the length of the supports that are used with the stock exhaust hangers. Has anyone experienced this? It appears that I'll need to add something to stop the movement on each side of the supports, but I wanted to see if anyone else has had this issue as it seems like a huge oversight. I haven't found much information about this through ECS or the forum so far, just bits and pieces from other exhaust systems threads where I see some mention of clamps for the exhaust hangers.

And to clarify, this isn't just a little left/right movement, it's enough that the tips could touch one side of the diffuser and move far enough to touch the opposite side.

I installed an ECS Exhaust on my S4 a few months ago, I have noticed there is more movement than the stock exhaust. Mine does move far enough to touch each side of the diffuser, but this would only happen in extreme driving conditions. Under normal driving conditions there is some movement, but not enough to touch the sides of the diffuser. My only issue so far is struggling to get the tips on the drivers side lined up.
