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.

BORLA is committed to providing world-class exhaust products which surpass the expectations of our customers. To that end, our facility is complete with a state-of-the art test and development center where we are continually improving our manufacturing efficiency and standards. We 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, Header and Rear Section is made from austenitic stainless steel (superior to 409 or aluminized steel) employing mandrel-bent tubing, all-welded construction, and is designed for accurate fit and easy installation. Over 30 years experience and special merge collector technology provide the ultimate in power and endurance.

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.

Why 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.

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 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.

With over 400 internal muffler designs based on the technologies shown here, BORLA® offers exhaust systems to suit every vehicle, driving style and sound preference. Muffler body shapes, internal
core characteristics, flow dynamics and more are tuned and harmonized to maximize performance and pure driving excitement.

BORLA® ATAK™ (Acoustically-Tuned Applied Kinetics) technology is
designed for high-performance purists who prefer exhaust sound
over their stereos. ATAK™-equipped exhaust systems deliver the
highest available dB (decibel) levels in the BORLA® street-legal
lineup. And unlike inferior brands that lose significant sound
quality at higher volumes, ATAK™ is tuned like a graphic equalizer
to shape and focus sound waves for optimum high-volume output.
ATAK™ technology is based on specifically-tuned attributes of
the internal muffler cores, which are calibrated on a vehicle-byvehicle
basis to deliver the most desirable sound.

S-TYPE

THE HEAD-TURNING SOUND OF STRAIGHT-THROUGH POWER
Just the right blend of packing filament, straightthrough core dimensions, core perforation pattern, and cylindrical shape to deliver the intoxicating BORLA® “Sound of Power” with every squeeze of
the throttle.

MULTICORE

HIGH FLOW & POWER, WITH RACE-OPTIMIZED SOUND
The combination of flow and sound characteristics provided by our Multicore mufflers is noticeably unique. A bit mellower than the S-Type with a distinct growl and race-proven performance.

TOURING

HIGH PERFORMANCE WITHOUT THE ROAR
The streamlined oval shape of our Touring mufflers allows the addition of more capacity within the muffler which results in a ride that is quieter than other BORLA® models. A single-core, high-flow
design adds power and driving excitement with a sound that is deep and throaty but just slightly louder than stock at open throttle. These mufflers are for the “sleeper” crowd.

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. In fact, we offer the broadest line of emissions legal exhaust; and, as long as the OE catalytic converter location is maintained, installation of a BORLA will not affect your factory warranty.

It is recommended to have your BORLA 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. We engineer and manufacture all our exhaust products in the USA of premium grade austenitic stainless steel and back our street exhaust with a Million-Mile Warranty.

BORLA supports "Tread Lightly!" and reminds you: When you go off-highway, go easy on the environment.
