i was just wondering wich one was better. my brother has a kx 80 and he is wondering wich is better.he is prabably going to get one. thanks

 

personally i have had problums with the mounts onthe procirct cracking

 

i'm not sure which one is better but just make sure your brother knows its not going to help a lot. Motocross bikes are tuned so that they get maximum power unlike a quad. When you put a pipe on it, it may change the power curve and add a little more power but don't expect it to make it into a whole new bike.

 

I have a 97 YZ80 and my friend has a 96 KX80 and we raced stock and they were dead even except the kawasaki had more bottom-end, I got a Pro circuit and he got an FMF. We raced after the new pipes and myn is a lot quicker and faster on top. The fit and finish of both look great
