MM Panhard Bar and Flowmasters, Will it fit? Tips?

I'm getting ready to order up some parts for upgrading my car in May. I've wanted to do the MM panhard bar install for a long time and I'm finally going to pull the trigger. Has anyone done that install with a Flowmaster cat-back before (either 17112 of 17212 American thunder systems)? Does the MM bar really clear the Flowmaster exhaust pipes? Their web site says that it's compatible with Flowmaster systems made after 2000 or the stock exhaust. I'm mainly asking so that I know what I'm in for when this fun project starts. If I'm going to have to start cutting and splicing the exhaust, I would rather know this in advance rather than be surprised and not plan the extra time required. I would really appreciate hearing from someone who's actually done the install, and I would also appreciate any other tips or "heads-up" advice that you can provide.

Thank you =)

Thank a million for the input. That's a big concern and makes sense with the lower roll center. I'm rumming 255/45's right now.

BTW: What does your car run in the 1/4? That sounds like a great setup.
