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 T-304 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.

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 aircraft-quality T-304 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.
