The pipe you pictured is not going to perform much better then your stock exhaust. The proplem you will run into with aftermarket CRF50 exhausts is the mouting bracket on the sub-frame. The 125 motor in your C3 has a taller cylinder then a CRF50, so it is going to push the whole exhasut system farther forward, making the fixed rear bracket on a exhasut designed for a CRF50 not line up on your sub-frame. You can either relocate the mount on your sub frame, build a bracket or get an exhasut with a non-fixed rear mount.
