so i've looked and looked at all the vendors and BMW car parts websites like ECS, UUC, Turnermotorsports, understeer, ebay, etc etc and could not find a mid-pipe/test pipe/track pipe that replaces the catalytic converter.
does anyone know if anyone makes them specifically for our cars that bolt right up? Does anyone have an OEM cat mid-pipe section preferably gutted out they'd like to sell me?
