It uses Borla's patented straight-through, multi-core design to increase exhaust velocity and free up power while producing the distinctive Borla Sound of Power. The system is built from premium T-304 austenitic stainless steel with ultra-smooth mandrel bends and CNC manufacturing for an accurate fit. Borla exhaust is handmade in the USA and backed by the Borla Million-Mile Warranty.
