Nissan 240SX Performance Modification/KA24DE and KA24E/Exhaust
A free-flowing exhaust has been know to create increases in both horsepower and torque across the RPM range in the KA24-powered 240SX.
Unlike other 4 cylinder engines, the KA24DE responds very well to most of the 3" exhausts on the market. Improvements have been made across the entire powerband, with no loss of torque.
