• Utilizes a 4-2-1 [Tri-Y] layout that results in improved throttle and rev response throughout the low to high range of the RPM band.
• The Flat-4 engine 4U-GSE and FA20 becomes sportier with an improved responsive driving feel, due to the mid-range torque curve becoming linear and eliminating the low torque curve valley of the factory engine.
• Optional Super Catalyzer is constructed in 130cpsi, and optimizes the exhaust system by reducing weight from having stock catalytic converters (x2) down to 1, and also minimizing exhaust gas flow restriction, meanwhile meeting emissions standards all in one catalytic converter configuration.
