I Need Some Help With a Set of PI Center Dumps

[yamaha98sx700]

I have a set it Power Inc. Center Dump pipes that I picked up on E-Bay last year. They came without the springs. If someone has a set of these on there sled could you please help me out and take a few measurements off the springs, (Coil diameter, spring diameter, and spring length.). I also need the # of springs, and maybee a picture of how they are installed. I know that I am asking allot, but I hope someone cane help me out with this, it would be much appreciated.

Thanks
