Borla Performance Industries is the pioneer and leader in the design and manufacture of stainless steel performance exhaust. The number 78 on our race team vehicles pays homage to the year 1978, when we began by building exhaust systems for Rolls-Royce and Ferrari concours classics. Since that day over four decades ago, we have evolved into the premier exhaust brand of today's most popular cars and trucks.

Borla is committed to providing world-class exhaust products which surpass the expectations of customers like you. To that end, our facility is complete with a state-of-the-art test and development center where we continually fine-tune manufacturing precision and standards. We have trailblazed a variety of improvements in exhaust design, leading to many US patents for innovative technology and numerous Best New Product industry awards.

Unlike any other exhaust, Borla systems are designed from scratch on a vehicle-by-vehicle basis. Every car and truck has unique mechanical and acoustical properties, all taken into account as we spend countless hours optimizing muffler body shapes, internal core configurations, flow dynamics and sound. What’s more, Borla offers you a choice of three exclusive sound technologies — ATAK®, S-Type and Touring — to suit your taste in sound volume and character.
