Regarding the modification of the exhaust, I believe many of my friends have known about it. The most useful thing for power boosting is the head section, not the mid-tail section. The head exhaust is most directly responsible for the discharge of exhaust gas from the engine and the turbine, and the three-way catalytic converter is also gathered here. After the car is modified, if it is not upgraded, whether it is the engine or the turbine, the exhaust back pressure will increase, and the air cannot be effectively discharged, resulting in problems such as excessive temperature and the inability to rapidly increase the speed, shortening the life span, and today What I want to recommend to you is a head exhaust for Audi S5 from JBOM.

Generally speaking, car manufacturers are subject to cost control. For the original car three-way catalytic converter, high-density ceramic products with low cost are generally used. The too small three-way catalytic aperture is easily affected by carbon deposits and sulfides in the exhaust gas. Blockage, resulting in low exhaust efficiency and not very long life, so why we often hear that some German models upgrade 2-stage ECU products and need to replace the head section, the answer is here.

Picture: JBOM is a well-known head-end exhaust manufacturer from Taiwan. Since its establishment in 1999, it has more than 16 years of experience in supporting the original factory. If you are interested in this brand, you may wish to move to "Breathing Professional" Three-way catalytic converter brand JBOM introduction" to understand.

Picture: As a representative of the word "performance car", the Audi S5 model with 3.0 supercharger is undoubtedly the dream lover of all car enthusiasts.

Editor's comment: Regarding the upgrade of the exhaust, we can actually understand that the head section is responsible for power improvement, while the mid-tail section is responsible for sound and appearance. Therefore, for the real performance porcelain, the upgrade of the head section is very necessary. As a manufacturer of the main head section, JBOM believes that its years of experience in supporting the original factory have contributed to it. In the face of many other big brand products, Might be an affordable option.
