N1 Evo Cat-Back Exhaust System

The A'PEXi N1 Evolution catback exhaust system is engineered to enhance the performance and sound of your 1990-1997 Mazda Miata NA. This exhaust system is built using polished SUS304 stainless steel for both the piping and muffler, ensuring exceptional durability and resistance to corrosion from environmental factors. The N1 Evolution features a straight-through design racing muffler paired with free-flowing, mandrel-bent piping. Specifically for naturally aspirated applications, the piping diameter ranges from 50mm to 60mm, with a 90mm tip diameter and a round, single-wall, straight-cut tip style. Born from A'PEXi's experience in the N1 endurance series, the N1 Evolution is an evolution of the original N1 muffler. It combines the proven performance of the classic design with lightweight, fully polished stainless steel construction. The use of robotic TIG welding on the SUS304 stainless steel canister guarantees an immaculate finish and long-lasting reliability. This design minimizes pipe bends to allow for greater exhaust flow, contributing to performance gains. Fitment is specifically for the Mazda Miata NA chassis (NA6C, NA8C) with B6-ZE and BP-ZE engines, covering model years 1990 through 1997. It is designed for the 2-door coupe body style.
