The BORLA(r) 11969 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 S-Type sound level has been tuned for the CX-5?s 2.5L engine to provide a slightly more aggressive sound than the stock exhaust. BORLA(r) guarantees a drone-free exhaust system for a comfortable driving experience. Ultra-smooth mandrel bends ensure maximum flow & power, and precision computer numerical control (CNC) manufacturing ensures an accurate fit.
