BORLA(r) presents their Axle-Back system for the fourth generation Mazda 3 Hatchback. The exhaust system replaces the stock rear muffler and is a direct bolt-on part for ease of installation. Specifically tuned for the 2.5L Skyactiv engine, our S-Type Axle-Back delivers a sportier sound and a more exciting driving experience without any drone. It features 4" Chrome on T-304 stainless steel exhaust tips that properly fill out the rear bumper cutouts. Black Chrome tips are also available.
