The World Sport concept is A'PEX's interpretation of how each vehicle's exhaust system should have looked and performed right from the factory. Designed with the daily driver in mind, this exhaust series focuses on drawing out mid-range torque and engine response for optimal drivability on the street. The styling is subtle and elegant, but still retains characteristics of its racing origin. The result is an affordable cat-back exhaust system that makes the daily commute more enjoyable.

In the N-1 Endurance Race, efficiency is everything. With that in mind, the N-1 exhaust systems were born to satisfy the want for quick throttle response and to effectively handle the rigorous demands of high-horsepower engines. The pipes were engineered with the aid of sophisticated CAD systems to develop the straightest possible lines and least number of bends. The straight-through canister projects from the car at an angle, which helps smooth the exhaust flow. The canister is built from SUS 304 stainless steel and features a 115mm tip with aggressive style. The Super Silencer is included on selected models, which can reduce noise levels by up to 7 decibels. The N-1 Series Mufflers are available for both NA (naturally aspirated) and turbo-charged cars.

GT Spec Mufflers are our flagship line of exhaust systems. These race-bred exhaust systems were engineered to handle extremely high-horsepower applications. A'PEX is the only company in Japan to own and operate a 95mm (3.74 inch) mandrel pipe bender at this time. We proudly incorporate this 95mm piping on select applications to offer exhaust systems unmatched by any other manufacturer. Pipes for the GT Series are designed with minimal amount of bends and the canisters project at an angle like the N-1. The GT Series pipes and canisters are constructed of polished SUS 304 stainless steel. The 115mm polished tip give the GT Spec Mufflers an aggressive, yet refined style. All GT Spec Mufflers include the Super Silencer, which can reduce noise levels by up to 7 decibels.
