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.
The Borla PRO-XS 3-inch Inlet / 2.5-inch Dual Outlet Muffler is designed for high-performance exhaust systems that demand maximum flow and a refined sound profile. This 19-inch oval muffler features a free-flow internal design that significantly reduces backpressure, allowing your engine to produce more power and torque. Constructed from premium T-304 austenitic stainless steel, this unit is built to withstand extreme temperatures and environmental conditions without rusting.
Borla’s PRO-XS series is the industry standard for those who refuse to compromise on quality. This muffler is not only built for performance but also for longevity, backed by Borla’s famous Million-Mile warranty. Its natural mill finish is perfect for custom fabrication, allowing you to polish it to a mirror shine or leave it for a rugged, industrial look. Whether you are upgrading your daily driver or a dedicated performance vehicle, this muffler delivers the results you expect from the world’s most experienced exhaust manufacturer.
