    Just a quick question. I have a 2000 r6 and would like to convert the exhaust system into a moto-gp style exhaust that comes in the newer r6's (low, by the rearset exit). Can I have a custom-made exhaust of this sort under WERA's C Superstock rule?
    The Rulebook only says that I can replace the stock system with an aftermarket, so I'm not clear on this.

    As long as it passes the db rating you are good.

    well anything is "aftermarket" i have a short GP on my zx6r, i need to run to radio shack and spend $50 on a db meter to see if its legal. its a can for an R6 but that can goes with the stock cat (mines removed) the full systems the cans are much longer. fingers crossed!!! i cant do anything about it now. only plus is the mid pipe is real long

    Yeah, they do check once in a while. There is more sensitivity to noise at some tracks than others. Depends on if there has been complaints from the locals. I seem to remember issues at Jennings GP for one.

    well u can do the exhaust but ur not worried about the noise part? ill attach a pic of mine and since im at 105db (the max) you can see how long my mid pipe is and can. if yours is shorter u may run into trouble with the noise.
