APEXI N1 CATBACK EXHAUST SUBARU IMPREZA WRX / STi
APEXI N1 catback exhaust systems were born to satisfy the need for a quick throttle response and to effectively handle the rigorous demands of high-horsepower engines. Each APEXI N1 catback exhaust is built from SUS 304 stainless steel and features a 115mm exhaust tip with aggressive style. The APEXI N1 exhaust pipes were engineered with the aid of sophisticated CAD systems to develop the straightest possible lines and least number of bends. The APEXI N1 straight-through catback exhaust projects from the car at an angle, which helps smooth the exhaust flow. All APEXI N1 exhaust pipes are mandrel-bent to prevent any loss of efficiency. All APEXI N1 catback exhaust systems have a titanium-particle-based high-temperature paint to protect the exhaust pipes. The Super Silencer is included on selected APEXI N1 catback exhaust models , which can reduce noise levels by up to 7 decibels . Apexi Exhaust
