hey everyone,

I was just wondering what you are all using for an exhaust. I currently have a sparks big core and am afraid that it wont pass the sound test at the upcoming unadilla gncc in september. this will be my first xc experience and i dont need to have any hangups the day of the race. any suggestions would be great. thanks.

I could be wrong but I think only the pro and pro/am classes ever gets checked.

good luck and have fun with it!!

I know they don't check the afternoon classes anymore....Last year they checked the am, so I'm not for sure about it now.....Check the website

thanks for your help guys. I think I am going to just try and run my sparks system

They haven't been checking the AM. Not sure about PM.

Nope....Not checking this year then
