S-Type Dual 4-Inch Cat-Back Exhaust System

The Borla S-Type II Axle-Back Exhaust System (part number 11811) is engineered to enhance the performance and sound of your Chevrolet Corvette. It utilizes straight-through technology to maximize exhaust flow and power output, crafted from premium T-304 austenitic stainless steel for long-lasting durability and a premium appearance. This system is specifically designed for the 2009-2013 Chevrolet Corvette, featuring CNC manufacturing for a precise fit and easy bolt-on installation. The dual 4-inch round rolled angle-cut tips contribute to an aggressive, throaty exhaust note that demands attention. The tubing diameter is 2.500 inches, with dual 2-inch outlets. The Borla S-Type II system is compatible with vehicles that have or do not have the NPP (factory-equipped performance exhaust) system, though it does not include NPP valves. It is 50-state legal and California emissions compliant. This axle-back system comes with Borla's Million-Mile Warranty, reflecting the brand's commitment to quality and performance.
