Well I have narrowed my long search for the right pipe for me down to 2 pipes, the pro cicuit T-4 and the full yosh system w/ TEC. I found them both for just over 400 bucks each, which would you guys recommend from those two. I had a T-4 on my DRZ and I loved it, great power and responce, and also very light and well made. Also I can get the quiet core for times I need it. Second choice is the Yosh, never owned one, it is a little heavier and no quiet core, but it is the quietest one in regular form. It also seems to make more HP. What would you guys go for??? I finally have the money too, so I can't wait to figure it out, I hate that stock system, sounds like a lawn mower!
THANKS for any help

 

go w/ the yoshi. i love mine, i wouldn't traded it for any other pipe. i have raced a few raptors w/ a t4 and smoked them! i have almost the same set up as u ( k&n filter) and it works great!!
