The Borla Pro XS™ Stainless Steel Oval Exhaust Muffler (40363) is engineered for performance enthusiasts looking for an aggressive yet refined exhaust note. Designed with Borla’s patented straight-through technology, this muffler enhances exhaust gas flow, reducing backpressure while maximizing horsepower and torque. With a 2.25-inch inlet and outlet, a 14-inch body length, and a 19-inch overall length, it’s built to deliver both power and sound quality.

Crafted from premium austenitic stainless steel, the Pro XS muffler offers superior durability and corrosion resistance, ensuring long-lasting performance. Its multi-core design absorbs unwanted noise without restricting flow, unlike traditional chambered mufflers. This results in a deep, throaty exhaust tone while maintaining efficiency.
