So the rule book states that aftermarket pipes will be allowed, and we still have a db limit. I don't want to turn this into a shit storm with the pros and cons of allowing the rule, its in there get over it (you know who you are). I'll get to my point. I notice that WCSS has a track day before the first race weekend, do they have to follow the same sound limit WMRC does? I ask this specifically because I ran my KLX250 with a full open Muzzy system and no airbox lid at one of the WCSS track days and had no problems from any officials. I even made a point of taking a different line down the main straight while wfo for an entire session, and still no problem. My db meter tells me i am waaaaaaaaaaaaaaaay over the 88db limit with that bike, so what gives? I have a full Muzzy exhaust with quiet core for my ZZR 250 that I will race this year, and I plan on bringing my stock system too. It would just be nice to know before raceday if the bike will pass sound. Thank you.
