So as I was in the process of swapping the OEM air cleaner for a K&N CAI on the '03 I took notice that the little white muffler was missing the MARAUDER stamping on it. Did only the "04's come with the writing? Are they interchangeable? I know its kind of dopey to think about but I thought the Marauder stamping was a nice detail even if only MM owners would know about it.
