I ran the exhaust on both the .56 and .72 right into the cutout... No deflectors or anything used... The clearance on mine is more the adequate .... No problems at all... I did also however cut a hole in the bottom om my cowling for cooling and to allow me access to the LS needle on the carb... Whole thing works great....
