Gran coupes had down turn tips, I remember buying a 1970 cuda exhaust for my 74 back in 1983 at Napa, i then cutout the valance for round tip's
I was busted for having glasspacks that exited the side, i was pulled over by a then rare lady cop, i was driving and saw her pulled over a buddy and as i drove by I revved it up, well she chased me down and pulled me over and said she didnt like her ball's busted...hahaha
