The Borla 11968 exhaust system was developed specifically for the Mazda CX-5. Our Axle-Back system replaces the factory rear muffler and is a direct bolt-on product for ease of installation. The Touring sound level has been tuned for the CX-5’s 2.5L engine to provide a slightly more aggressive sound than the stock exhaust.
