BORLA® PERFORMANCE INDUSTRIES is the pioneer and leader in the design and manufacture of stainless steel performance exhaust.
We began three 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.
The performance advantages of a BORLA® are widely recognized. The top engine builders in the 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 horsepower and torque when you plant your foot, and improved gas mileage at cruising speeds.
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 we at 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.
Stainless Steel: 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 aluminizing, 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.
