the reason i posted on here is i couldnt find anything useful on google, and i do know from research not to use aluminum. aluminum bends... plastic flexes right? anyways the way the 3 speed is on this mt is very unique. there is 3 cb's and 3 spurs meshed up together. as far as i know there isnt even a slipper clutch. the gears are chain driven down to the center diff below the chassis. does a exhaust deflector change performance since its an extension on the pipe?
