MAP Race Catback Exhaust


The MAPerformance race catback exhaust is the most aggressive option for the Civic Si. With one resonator and no mufflers, the four tips give a unique design, with the two inside ones sticking out. This gives a great dynamic to the rear of the Si. The quad 85mm tips fill out the stock exhaust tip’s location perfectly. Weight is 11-pounds lighter than the factory system, with five solid hangers that keep this system perfectly in place for years. The mandrel-bent stainless steel tubing are all done in-house. The Race exhaust produces the most sound out of MAPerformance’s lineup for the Civic Si; however, it is still relatively friendly for daily drivers. Boost remained almost identical to the factory system, but the system lost peak torque, and both power and torque throughout the RPM band, only gaining a slight advantage at 5,000 RPM over stock. Even with no mufflers, the MAPerformance Race exhaust only got past 95db once at 4,500 RPM when it reached 99dB.
