James TheStradman's Nissan Z gets an upgrade from Fi EXHAUST.

While the stock exhaust on the Nissan Z is notably tame and restrictive, our high-flow catback design transforms the driving experience. By replacing the restrictive factory catalytic converters, we've not only improved performance but also elevated the sound quality. You'll immediately notice a captivating rumble, particularly in the lower RPM range between 2,500 and 3,500, making your Nissan Z truly come to life.
