Apexi N1 muffler exhaust system for Mazda RX7.

In the N-1 endurance race, efficiency is everything. With that in mind, the N-1 exhaust systems were born to satisfy the desire 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.
