There shouldn't be any problem putting MW exhaust on a low deck motor. My oldest brother bought a brand new 64 Fury w/383 and one of the 1st things he did was put a complete MW exhaust on the car. I still remember he would un- cap the cut-outs when street racing, and you could hear the car being shut -off & coasting down the street in the middle of the night, trying to sneak in so our dad wouldn't hear him.
