Had a hole in the head pipe of my yoshimura titanium head pipe. Ordered a new stainless one (because of the cost difference) and when I went to put it on it doesn't fit correctly. There is about 1/8th inch free play between the exhaust port on the motor and the pipe when it's tightened up. I've tried to seat it several times with the same results. I will be calling yoshimura later today about the problem, but has anyone else ever had a problem like this?
