Hi this is Logan Forler and we have got some 1200s that we plan on running at deming this year and I was wondering what the rules are on having a wing slider and was is the header muffler rule. I tried opening the rules page and it wouldn't open up so if somebody could help me out that would be very appreciated thank you.

Logan, this years rule book should be posted again in the next day or so. But you should call Paul and he can give you the info you need. 360 393 0197

quick answer- wing slider is allowed, and muffler in the 09 rule book was a flowmaster #42441 with turndown.

yes, what sleepy said also spintech muffler OK cant remember # though ask tim @ MPS
