Looking at the Production photo posts, it looks like the Chally has the same "Suitcase" muffler system. Anyone know if that is indeed the case from what you've seen/heard? The concept was running Flowmasters so we knew that wasn't going to make it.

I hope to catch the Chally in Cleveland and look as well

 

From what I have read it is the same. The article said the exhaust was untouched unlike other parts of the car.
