WHAT CAN CAT BACK EXHAUST SYSTEMS DO?

Catback exhaust system refers to the last exhaust system after catalyst converter. Cat is the abbreviation of catalytic converter, which means exhaust gas catalytic converter, including mid pipe and exhaust muffler. Catback exhaust system is the most commonly chosen aftermarket exhaust system because they provide solid performance and sound gains without the great expense of purchasing a new catalytic converter. 

1. Exhaust Noise

The process of mandrel bending has become a key to success in cat back pipework bending, because the diameter of the bends is even – not pinched. When overall exhaust flow is increased, sound volume and quality improve as a whole. Many car enthusiasts like to make car modifications. The modified catback exhaust pipe reduces exhaust resistance, enhances engine horsepower output, and improves the appearance of the exhaust pipe. The disadvantage is that the noise will increase relatively after the change. So when you choose to modify the cat back exhaust, it’s best is to first check local laws. Noise pollution has become a sensitive legal matter in some areas, and police may choose to enforce laws against loud exhaust systems.

2. Larger-Diameter Pipes

The larger the pipe diameter, the smoother the exhaust flow. The average exhaust system on most passenger vehicles has been designed to meet bare minimum standards set within the automotive industry and provide levels of quiet auto manufacturers believe 99% of their customers demand. But in the performance world, a rule of thumb exists when it comes to diameter of exhaust pipes and performance modifications. As you tune your motor and add horsepower, you add larger exhaust pipes and freer-flowing mufflers in order get the full benefit of your gains.

3. Stainless Steel and Carbon Steel Exhaust Pipe

The majority of the performance cat back systems are made from stainless steel alloy blends that will never oxidize and corrode the way traditional steel can over time. For the customer seeking best value up front along with quality construction, you’ll find a variety of aluminized steel cat-back systems. Aluminized steel is carbon steel that has been coated with an aluminum-silicon alloy through a process called hot-dipping. The technique creates a tight metallurgical bond between the base metal (the carbon steel) and its alloy coating to give the new material a combination of steel and aluminum’s best characteristics. The underlying steel provides higher strength and rigidity than would be possible with all-aluminum construction, and the aluminum coating allows the whole system to reflect heat away more effectively. However, while the aluminum coating keeps pit corrosion from occurring in winter climates, aluminized steel can corrode if the aluminum layer is scraped or chipped away by rock hits, scrapes, or other impacts. Many cat back systems may be available in both aluminized steel and stainless steel versions.

4. Exhaust Tips

(1)Waterproof

The exhaust pipe will affect the driving due to water ingress during daily driving. If the muffler accidentally enters the water, start the engine immediately and let the water in the muffler drain as much as possible. The time is about ten minutes. This is especially important in the maintenance of the exhaust pipe.

(2)Antirust

There are many reasons for rust, such as high temperature weather, humid environment, sand and stone impact and hard object impact wear, and the rust prevention work is not done in place. It is suggested that the rust prevention work should be able to apply rust prevention oil in daily maintenance and carry out rust prevention treatment.

(3)Clean

If there is oil stain on the exhaust surface, it shall be cleaned in time, otherwise the exhaust pipe will turn yellow and discolored due to hot vehicle. At the same time, the adhesion of greasy soil will also affect its heat dissipation, thus affecting the overall performance.

By replacing the high-performance catback exhaust system for car, the engine can absorb more than one row smoothly, thus improving the power performance, which is also the most simple and effective car alteration method.
