Akrapovic is the only exhaust gas company that has its own titanium foundry and casting machines. With a workforce of 1,300 employees, everything is studied, designed, designed and manufactured in-house by Akrapovic in Slovenia. The issue of open pipes (little or no sound attenuation) or modified exhausts on motorcycles has always been a hot topic between supporters and opponents. For the nation`s capital, Manila, a draft “anti-silent” municipal ordinance aims to ban the use of modified open/quiet pipes. Despite the way it sounds, the author probably means noise-cancelling or open exhaust. A ban on mufflers – a device whose job is to dampen engine noise – would only make vehicles noisier. On the one hand, there are those who are in favor, arguing that the louder noise they make alerts motorists to motorcycles around them, making it safer. They also argue that it`s legal to sell replacement exhausts, so drivers can legally install these open or modified exhaust systems in their vehicles. A typical Akrapovic exhaust saves between 40% and 60% of the weight of a regular exhaust, especially if you order a complete exhaust system with catalytic racing systems and exhaust manifolds or manifolds via a conventional steel-based exhaust system. However, in line with the introduction of the new Motor Vehicle Inspection System (MIS), the Bureau of Land Transportation (OTL) is currently developing new rules and regulations to ensure that vehicles pass the inspection and receive new approval.
Among the most controversial is the proposed noise limit of 99 dB for vehicle exhaust. Until recently, the LTO had introduced a 115 dB limit nationally. However, it seems that this was still too strong as we now see the recommendation to lower it to 99 dB. To avoid confusion, guidelines have been issued on how to check volume. Akrapovic is proud to be part of the research and development team involved in the development of the next A90 Supra GT4 race car concept, which will race in 2020. This then helped them design the legal exhaust for the road of the regular A90 Supra road car. As specified in section 5.4.3.7 of the FIS, the exhaust or muffler of a motor vehicle shall not exceed 99 decibels at engine speeds of 2,000 to 2,500 rpm. If a particular vehicle fails the sound test, the LTO confiscates its front panel. The owner then receives the MVIS report after said test.
The popular Akrapovic premium exhaust systems for performance cars and motorcycles have been available in the Philippine market for some time through their designated dealers, marketers, and select online stores. But on September 18, 2019, representatives of Akrapovic Exhausts from Slovenia officially visited the Philippines and briefed media representatives, distributors and selected customers to discuss the brand`s history, future, products and the latest cutting-edge technologies. Akrapovic is a market leader in aftermarket, motorsport and OEM suppliers for titanium exhausts. Titanium is the main material of choice because it is incredibly lightweight, extremely heat resistant, and can withstand 1,000 degrees of continuous heat. It is lighter and stronger than traditional stainless steel, corrosion resistant and also lighter than Inconel, another heavy metal alloy used in motorsport. “It is prohibited to drive a motor vehicle on a highway if the motor vehicle is not at all times equipped with one or more silencers operating continuously and of sufficient capacity for the engine and equipped with an exhaust system to prevent the leakage of excessive vapours or fumes and abnormal noise.” Many people really like noisy exhausts. From motorcyclists and casual owners to enthusiasts and motorists, many want to hear the roar of their engines. In fact, modifying the exhaust is crucial for a less restrictive airflow to produce more power.
The volume of most of these high-performance aftermarket exhaust systems are just the interesting side effects. Once it is a municipal ordinance, offenses for the first violation and removal of the modified muffler or exhaust pipe will be punishable by a fine of PHP 1,000. For secondary counterfeiters, this is PHP 3,000 plus removal of the modified muffler or exhaust pipe. A third offence is punishable by a fine of PHP 5,000 plus removal of the modified muffler or exhaust pipe. To measure the sound level of a vehicle, a sound level meter is positioned at several key locations. The first position is located at an angle of 45 degrees to the centre line of the exhaust, parallel to the ground and about 0.5 m from the rear of the outlet.
