Product Description

Borla Cat-back & Axle-back exhaust systems feature patented straight-through and multi-core technology to unleash hidden horsepower. Increased exhaust velocity adds power, driving excitement, fuel economy, and the distinctive BORLA® Sound of Power respected by motoring enthusiasts everywhere.

This 2.5″ diameter into dual 2″ BORLA® Axle-Back system is engineered for the 2019-2025 Mazda 3 Hatchback models, designed to replace the stock rear muffler via a direct bolt-on installation that uses the OE mounting points. The system delivers the aggressive S-Type sound profile, offering a much sportier tone than stock while maintaining refinement and minimizing drone in the cabin.

Tip finish is the main variation: the 11970 version comes with bright-chrome polished 4″ tips, whereas the 11970BC version uses 4″ black chrome tips for a different visual style. Constructed entirely of premium T-304 stainless steel with ultra-smooth mandrel bends and precise CNC machining, these exhausts not only enhance sound but also ensure durability. BORLA’s patented straight-through and multi-core technology boost exhaust flow and performance, while the system is backed by their Million-Mile Warranty for peace of mind.
