Do you mean the stainless steel performance (race) can?  If so,
did the dealer also download the proper EFI tune for the
performance can?  If not, your engine is running quite lean, as
the performance tune, among other things, richens the mixture to
account for the low back-pressure flow of the performance can. If
you have the standard tune, you risk burning exhaust valves. Have
the dealer verify that the proper tune has been loaded.
