i have the side pipe and i don't find any handling issues with it. i like the sound of it, it has a unique sound to it and great performance. the only thing i don't like about the rear pipe is there is nothing protecting the bottom of the pipe. atleast on a baja with a rear pipe there is a type of bumper on it were as there is nothing on a xb. if your running in some ruff area whats stoping something from hitting the bottom of the pipe or grabing it. or if you take a big jump and land straight on the ass. me, i'll run rear pipes on my baja but not on my xb.
