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.
Big power gains with a mellow tone and quality that’s second to none;
that’s Borla’s mission and it goes into every exhaust component the
company builds. 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.
