nothing but cpi's will touch my 421...or any other motor i own after that. not only is it a great pipe but if something goes wrong cpi has great customer service !
cost me $210 to rechrome 2 oof drag pipes, cut 3 1/2 " of the silencer, mount on all factory mounting brackets and fix a bend in the neck of the pipe that i figured would ruin the pipe. that was also including shipping....back not there.
