Why Choose Stainless Steel on Car Exhaust?

Choosing performance exhaust can be baffling. There are so many misconceptions and misinformation surrounding the choice of materials as well as manufacturer.

Millions of car exhaust systems are replaced each year because of poor performance and corrosion. Day in and day out, automotive exhaust systems are exposed to mixture of carbon monoxide, moisture unburned hydrocarbons, oxides of nitrogen and more. These gases condense and ruin the system internally. The external deterioration is also contributed by corrosive salts, mud and moisture. These elements combined with high temperatures, vibration, uneven road surfaces, emission control requirements and different traffic patterns make it simple to decipher the need for a durable and lasting car exhaust system. This is the main reason why auto experts suggest stainless steel exhausts over other materials.

Other car owners think other materials like chrome is good choice but recent studies boosted by auto experts attest to the efficiency and durability of stainless steel car exhausts. They are engineered to withstand destructive conditions. Auto experts suggest Borla exhaust and other stainless steel exhaust system. These exhausts are said to be guaranteed for a million miles.

Aside from the misinformation regarding the material used, there is also a misconception regarding the exhaust’s size. Some vehicle owners believe that the bigger the exhaust is the better. In fact, even some manufacturers seem to feel the same way. Studies show that for street driving, big pipes just take energy out of the system. It is done by slowing exhaust gas velocity or by cooling the gases. A good sign that energy has been lost is when exhaust leaves the port at 1500 degrees or more and the tailpipe slowed to 150 degrees. Uninterrupted flow and velocity are considered real-performance-making factors.

Low frequency range has energy. However, big pipes increase the low frequencies resulting to eerie droning and roaring sound. As oppose to big pipes, Lincoln Aviator Borla exhaust is specifically engineered to achieve less restriction. Further, it keeps the frequency and velocity high so the main sound is reduced and is delivered behind the tailpipe.

Some of the stainless steel car exhaust systems available in the market these days are built of aircraft-quality T-304. It is true stainless inside and out, not aluminum, not mild steel, not coated aluminum, not just enveloped with stainless on the outside for show.

Car exhaust coatings extend the life of mild steel however; coatings suffer at the weld points. Compared to aluminized steel, 100 percent steel is has the highest chromium content, making it the most resistant to corrosion. Moreover, it is the most reliable material for a long-lasting car exhaust system.

Nowadays, the car exhaust system comes with a diverse design. This is due to the experimentations made by most manufacturers. Diversity in style is resorted to boost the overall appearance of the car.
