Borla Performance Industries was founded in 1978 and remains America's premium cat-back exhaust brand. Every Borla system is hand-built from T-304 austenitic stainless steel and backed by a million-mile warranty — the OE choice for Camaro ZL1, Mustang GT350, and Chevy Corvette.
Designed for truck and custom exhaust projects requiring a long-body muffler, the Borla Touring Specialty Muffler (401665) delivers a refined performance upgrade. This muffler features a 2.75-inch center inlet and outlet, a 24-inch body, and a substantial 7.75-inch diameter, offering a balance of smooth flow and a more subdued exhaust note compared to the S-Type. Its "Touring" designation ensures a comfortable yet enhanced driving experience.
This Borla Specialty Muffler is engineered for weld-in applications, providing a robust and high-quality solution for custom exhaust systems. Backed by Borla's legendary Million-Mile Warranty and made in the USA, it represents a smart investment in your vehicle's performance and sound. Upgrade your exhaust with Borla's trusted quality, available at GGCRACING.
