The Borla S-Type axle-back for the fourth-generation Mazda 3 Hatchback replaces the stock rear muffler as a direct bolt-on. The 2.5in into dual 2in system is tuned for the 2.0L and 2.5L Skyactiv engines and delivers a sportier sound and a more exciting drive without any drone. It features 4in round bright chrome on T-304 stainless steel tips that fill out the rear bumper cutouts. A black chrome tip version is also offered as 11970BC. Ultra-smooth mandrel bends ensure maximum flow and power, and precision CNC manufacturing ensures an accurate fit. This axle-back installs behind the factory catalytic converter and retains all factory emissions equipment. It is made in the USA and backed by Borla's Million-Mile Warranty.
