I Need Some Help With PI Center Dump Pipes

[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!

Thanks! This helps a little. It looks like stock Yamaha exhaust springs. Does anyone have any pictures of where they hook into the cylinders.
