Hello All,
I have a couple of tuned pipe questions. I am running a stock ZEN260 with a 2 inch band pipe on it. My current exhuast port to center of pipes 2 inch band is 13 1/4 inches, my current Max RPM is 15800. Now for my questions, do I have enough RMP's to start adjusting the tuned pipe length?? When I do start adjusting the length how much of a increase in RPM am I going to see 10's or 100's or 1000's. I guess I need to know exactly what I am looking for to know when I have the pipe running correctly.

Thanks for any comments

Steve
