2010 90cc pipe

[Bens Dad]

Does anyone know if I can run a 2009 50cc stock DRR in the atva nationals with the stock 50 pipe, or do I need to change it to a 90cc pipe to be legal?

stock is stock, however I saw the difference last night of what the 2pc pipe will do for a 70 versus one with the older one.
If they will let you run the newer pipe, do it!

Thanks for the reply I need to know if I can run the 09 stock pipe and be legal . My 4 year old rides so good ,his older brother is 6 and he has a 70 mod, and a 2010 50 limited built by hetrick and can bearly take him. I dont want to change unless I have to
