Efficiency gains in rotories never cease to amaze me when increasing airflow.
My built 3-rotor with a Borg-Warner S-400 turbo acheived a 100 horsepower gain on the dyno at 17psi when the exhaust system was simply removed at the downpipe. This was a quality exhaust with no cats, not stock! My NA 2-rotor 6port gained over 40hp by removing the cats and replacing the exhaust with an Apexi GT N1 and a K&N intake. That is on a motor that comes stock with only 148hp!
