new cpi big bore pipe for my ken oconnor racing long rod 240 motor thats almost done. some key features of this pipe that impress me are the oringed head pipe where the flange slips in, billet rebuildable silencer show quality chrome plating and man the chamber of this pipe is huuuuuge definayely the nicest built pipe i have seen yet for the 240 blaster. and yes they make a smaller version of this pipe for stock type motors
