I used one on my 02 CR250 because my stock flange cracked too. As I understand it, this is very common on the 02 CR250.

As for power increase, expect nothing because that's what you'll get. In terms of changing the powerband, again, expect no change. If you really, really want to feel a change, you will ... but it won't be real, IMHO. :p

It's still cheaper and stronger than stock so you should get one though. :thumb:

I put a boyesen flange and a boyesen RAD3 valve on and noticed more powe r on the low end on my 2003 cr250

I also noticed a huge difference on my dads 02 cr250r when I put the rad valve and the exhaust flange on at once. I think it is better than any pipe silencer combo because it really feels the powerband in.
