what do you guys think

UMMMM your new gasket is not even sealed tight.That gasket should be pinched tight between the two flanges.The Guy at the muffler shop must be a Moron.
I always use high-temp RTV on my collector gaskets.They seem to last alot longer when I do this.Even if you blow both gaskets the pipes should not come loose.There is somthing wrong here.Wrong type of flange? wrong gasket ? Or both. Jim
