BORLA PERFORMANCE INDUSTRIES is the pioneer and leader in the design and manufacture of stainless steel performance exhaust systems in the USA. They began two decades ago as a manufacturer of exhaust systems for such "concours classics" as Rolls-Royce and Ferrari cars and have evolved into the premier manufacturer of today’s performance vehicles for the street, off-road, and racing.


About Borla "BORLA is committed to providing world-class exhaust products which surpass the expectations of customers. To that end, their facility is complete with a state-of-the art test and development center where continued improvements are made to manufacturing efficiency and standards. BORLA have pioneered a variety of improvements in the design of performance exhaust systems. Alex BORLA currently holds several US patents for innovative exhaust system technology, and the company has won numerous "Best New Product" awards in the industry. Every BORLA Cat-Back™ system, Manifold and Rear Section is made from austenitic stainless steel (superior to 409 or aluminised steel) employing mandrel-bent tubing, all-welded construction, and is designed for accurate fit and easy installation. Nearly 30 years experience and special merge collector technology provide the ultimate in power and endurance.

The performance advantages of a BORLA are widely recognised. The top engine builders in the (US) racing world rely on BORLA exhaust for maximum performance. In fact, BORLA 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 BORLA exhaust for the street, providing 7-10% increased power and torque when you plant your foot, and improved fuel economy at cruising speeds.


Why Stainless Steel?

Effect of chromium content on oxidation  

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. BORLA systems are built to withstand these destructive conditions -- we guarantee it for a Million Miles.

BORLA exhaust is built of aircraft-quality austenitic stainless steel -- stainless inside and out, not mild steel, not aluminum, not coated aluminum, not just wrapped with stainless on the outside for show. Coating techniques, such as aluminising, can somewhat prolong the life of mild steel, but coatings suffer at the weld points. And, comparing aluminized steel to T-304 stainless steel is like comparing gold-plated metal to solid gold! 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. In our twenty-year experience, we have found the 3/8"--1/2" flanges are so thick they will never affect the performance or longevity of the system.


Choosing The Right Performance Exhaust

Today, choosing performance exhaust can be confusing. A common misconception is that "bigger is better". Many enthusiasts, and manufacturers too, seem to feel that very large diameter pipes are the only way to go for muscle car performance, while BORLA have found for street use, big pipes just take energy out of the exhaust, both by slowing down exhaust gas velocity and by cooling off the gases. While exhaust may leave the port at 1500 degrees or more, at the tailpipe it’s down to 150 degrees -- a sign energy has been lost. Velocity and uninterrupted flow are the real performance-making factors.

Furthermore, it is the low frequency range that has energy (the sound you can feel inside the car); big pipes increase the low frequencies, making an uncomfortable roaring or droning sound. A BORLA exhaust system, on the other hand, is designed for less restriction, keeping the velocity and frequency high so the main sound is behind the tailpipe.

Late model cars and trucks are computer controlled to such an extent that it may take a period of time (600-800 miles) before the computer reprograms to reflect the improved flow characteristics of your new BORLA exhaust system.

The distinctive look of BORLA’s unique Intercooled Tips™ are a common sight on show cars as well as the hottest street cars around the world.

It is recommended to have your BORLA system professionally installed; however, if you choose to do it yourself, anticipate approximately two hours for a system install and approximately six hours for header installation. Compare the shipment contents with the ship list before you begin, and make sure the tip(s) line up, working and tightening toward the front of the vehicle.

BORLA doesn’t stop with unsurpassed technology. BORLA engineer and manufacture all exhaust products in the USA of aircraft-quality T-304 stainless steel and back street exhausts with a Million-Mile Warranty.
