Yoshimura's AT2 isn't just another slip-on that promises the earth and delivers a slightly raspier idle note. This is a proper full system that Yoshimura's engineers in Chino, California have been sweating over with their Faro Arm Laser Scanners and CAD programs as if they're designing a bleeding fighter jet. Looking at that aggressive end cap design, you'd be forgiven for thinking they nicked some blueprints from Lockheed Martin!
