The Borla S-Type axle-back exhaust system for the fourth generation Mazda 3 Sedan is a 2.25 inch diameter into dual 2 inch design that replaces the stock rear muffler as a direct bolt-on. Tuned specifically for the 2.5L Skyactiv engine, it delivers a sportier, more exciting sound with no drone and finishes with 4 inch round bright chrome T-304 stainless steel tips that fill out the rear bumper cutouts. Borla cat-back and axle-back systems use patented straight-through, multi-core technology with ultra-smooth mandrel bends and CNC manufacturing for increased exhaust velocity, added power, and an accurate bolt-on fit. Because this axle-back system mounts behind the factory catalytic converters, it is 50-state emissions legal. Every Borla exhaust is handmade in the USA from T-304 stainless steel and backed by the Borla Million-Mile Warranty.
