Looks the same as the ones on my 04 KP, and yes they are labeled Victory Performance (on the covers) and appear to be a deal Victory worked out with Vance and Hines in these early years to have them make the Stg 1 pipes for the KP, and appears to be Vegas also from your pics.
I found this out on the S&S intake brochure I got when i put that intake on my KP....part of hte purchase included an S&S Calibration Map File and the one i chose was labeled as follows:
S&S Map File # 54-0111, details: 2003-2005 Veg/Kng Pn/8-Ball 92CI S&SAC/STGIVictory Performance (V&H)
