The A'PEXi N1 Evolution R Ver.2.0 Catback Exhaust brings the iconic N1 exhaust design to both generations of the Toyota 86 / GR86 and Subaru BRZ platform. Developed from A'PEXi's motorsport experience in the N1 endurance series, the N1 EVO-R combines a straight-through racing muffler design with free-flowing mandrel-bent piping for improved exhaust flow, aggressive styling, and long-term durability.

Constructed entirely from polished SUS304 stainless steel, the N1 Evolution R uses a minimal-bend exhaust path to reduce restriction while maintaining the unmistakable angled N1 muffler appearance. Robotic TIG welding and fully polished piping give the system a premium finish that looks just as serious as it sounds.

A'PEXi N1 Evo R V2 Overview

Why We Like It

The N1 is one of those exhaust designs that is instantly recognizable, and the EVO-R takes that formula further with full stainless construction and cleaner fabrication. It is a great fit for owners who want a more aggressive exhaust with genuine JDM heritage rather than something designed to disappear under the rear bumper.

Sound & Performance

The N1 Evolution R is built around a straight-through muffler and low-restriction piping layout, giving the 86/BRZ platform a more aggressive exhaust character while improving flow compared to the factory system. Its track-inspired design prioritizes a direct exhaust path and responsive feel.
