You pretty much have 2 choices for inframe drag pipes.
CPI's and Shearer's
CPI's come on a little sooner and Shearer's have a little more top end. I went with CPI's on my banshee because I wanted the power to come on a little sooner. Both pipes come with ok chrome. It isnt the best, and has been known to peel. If you want show chrome then you need to get them from www.cascadeinnovations.net That is where I got my CPI's from. If your wanting the CPI's with standard chrome or bare steel then PM Frogger on here, see what he can do for you.
Here is a pic of my CPI's. It will be a huge change if you go from Pro Circuits to CPI's or Shearer's. I ran T5's on the motor in my sig before I got CPI's. It was a huge change going from the T5's to CPI's
As for the other bike running T5's what kind of port job does it have?
