Borla is the leader of stainless steel performance system, who began two decades ago as a manufacturer of cat-back  system for cars such as BMW and has evolved into the premier manufacturer of today's performance vehicles for the street, off-road, and racing.

The quality of this system is a world class product which surpasses the expectations of our customers.  The Cat-Back system have pioneered a variety of improvements in the design of performance exhaust systems and currently holds three US patents for innovative exhaust system technology. Every Cat-Back Exhaust System employs mandrel-bent tubing, all-welded construction, and is designed for accurate fit and easy installation. Warp-free 3/8"-1/2" thick flanges and special merge collector technology provide the ultimate in power and endurance.

 The performance advantages of this exhaust system are widely recognized. The top engine builders rely on this product for maximum performance. In fact, Cat Back Exhaust System is at the forefront of the movement toward responsible racing with our full line of patented, award and race-winning racing mufflers that not only maintain a race engine's power, but in some instances actually add power. This technology is incorporated into cat back exhaust system for the street, providing 7-10% increased horsepower and torque.

Millions of exhaust systems are replaced every year due to corrosion and poor performance. Automotive exhaust gases are a mix of carbon monoxide, oxides of nitrogen, unburned hydrocarbons and moisture. These gases condense and attack the system internally. Elements such as corrosive salts, moisture and mud contribute to exterior deterioration. These elements combined with equipment vibration, high temperatures, emission control requirements, uneven road surfaces, and varying traffic patterns make it easy to understand the need and demand for a long-lasting exhaust system. These systems are built to withstand these destructive conditions.

Cat Back Exhaust System is built of aircraft-quality T-304 stainless steel inside and out. T-304 stainless steel has the highest chromium content, making it the most resistant to corrosion and therefore the most desirable material for a long-lasting exhaust system. Note: Only the flanges are not stainless.
