Construction & Design

The Borla Touring Cat-Back Exhaust System is built from premium T-304 stainless steel, a high-grade material known for its exceptional resistance to corrosion and heat. This is a significant upgrade over lower-grade T-400 series stainless steel commonly used in aftermarket exhausts, ensuring greater durability and longevity even under harsh driving conditions.

Each component features ultra-smooth mandrel bends that preserve exhaust gas velocity and reduce turbulence, maximizing power output.

The Borla Touring system is engineered to improve exhaust flow, which can translate into increased horsepower and torque by reducing backpressure. The patented straight-through and multi-core technology delivers a clean, aggressive exhaust note that is distinctive yet refined, avoiding the overly loud or droning sound common with some aftermarket systems. This makes it ideal for drivers who want enhanced performance without sacrificing comfort or attracting unwanted attention.
