If I do a search of "exhaust" in the WMRC rules, the word appears in very few places. As I mentioned in my earlier post re the 2013 WMRC rules and the EMRA rules, I could not find a reference to the allowance of an "aftermarket exhaust" in Chapter 8 (the supersport rules), which are incorporated into the Chapter 8a 250 gold cup rules.
It does seem odd to me that the 2013 WRMC rules would allow electronic fuel injection control modules, but not allow aftermarket exhausts.
There is a reference to "exhaust" in the Chapter 8a 250 gold cup of the WRMC rules:
8.12a When racing at WMRC, all exhaust systems must meet sound requirements of 88db; and, when racing at PCMRC (Greg Moore Raceway), all exhaust systems must meet sound requirements of 78db
Why would WMRC refer to sound tests if you have to use a stock exhaust in the 250 Gold Cup class?
There is an interesting list of mods to a "2012 Championship winning 250 Gold Cup CBR 250" for sale on the WRMC website:

Very sharp looking bike, but not a good one to buy for the EMRA 250 Gold Cup class. You would be paying a lot of $$$ for mods that would not be allowed.
