If the original exhaust rusts or needs to be replaced for some other reason, you can of course do so. Beautiful optics and other noises are also not a problem. However, you should note that in Switzerland you can only use original exhaust systems or exhaust systems registered in the vehicle`s registration document in road traffic. If you are really checked on the road, EU reports on replacement exhaust systems are often accepted, but no manufacturer can guarantee this. So make sure you have a license. Adjustment with a flap exhaust – what is allowed? In Switzerland, the Road Traffic Office requires a declaration of suitability for the legal modification of the vehicle by an exhaust system. If it is mentioned in the respective product description that a declaration of suitability is attached or provided, you can assume that the exhaust system is legal. This means that the declaration of suitability will be given to you free of charge after delivery of the exhaust system. By law, a legal exhaust system cannot be noisier than the factory-installed exhaust system, taking into account a tolerance value. For reasons of cost and comfort, original exhaust systems are manufactured by the manufacturer in relatively small diameters and chamber acoustic dampers. The sports exhaust can contribute to increased performance if the entire system is replaced. This is a laborious adjustment measure, which is why in most cases only the exhaust is open. This in turn improves the appearance and acoustics, nothing more.
In most cases, changes to the exhaust are not subject to notification or inspection. However, there must then be confirmation from the supplier indicating exactly what type of vehicle the exhaust system is intended for. You must place this confirmation from the supplier in the vehicle registration document and always take it with you in the car. If your attachment does not have such confirmation, it must be verified by DTC or FACT. These checks are also required for insurance coverage. If it is not available, the insurance company cannot intervene in case of damage. In general, only original exhaust systems and identical systems are exempt from registration. However, it is also possible to mount sports exhaust systems or similar.
These products shall not be subject to inspection and shall not be declared if approval is available for the vehicle type in question. The RL-2a (motor vehicle) and RL-2b (motor vehicle) indicate which approvals are recognized. For systems imported from abroad, you should note: The importer must confirm for which type of vehicle the system is intended by the manufacturer. The content must at least be clear: the subject of noise, due to a flap exhaust system, is currently in turmoil in Switzerland. Although the adjustment with a front spoiler, lowering or foil has no influence on the background noise of a vehicle, the same is of course true with a modified exhaust. And there is almost everything to buy, what the driver`s heart desires and many that have nothing to do with the subject of such boring tuning. In particular, noise caused by modified vehicles is increasingly a thorn in the side of residents and authorities. In Switzerland, too, they want to eliminate roaring engines in road traffic as much as possible. And here, as in Germany, the authorities are particularly concerned with noise generation by means of flap exhaust systems. Here, especially during the switching process, a pop is often generated. But even in Switzerland, these plants are not banned in principle. The legal situation in Switzerland only prohibits the deliberate generation of unnecessary noise in residential and recreational areas and the modernization of flap systems in exhaust systems that did not have this function before.
Swiss Tuning AG does not issue a declaration of suitability for BMW M Performance exhaust systems alone. BMW M Performance sound damping systems are of course approved by Europe/Switzerland as an independent technical unit according to R51/R59. If the traffic office requires a corresponding confirmation, this can be requested directly from BMW. Currently, you can find more than 16,000 items in the categories rear acoustic shock absorbers, pre-acoustic and medium-acoustic shock absorbers, presonic and medium dummies, catalytic converter systems, cat-free downspouts, downpipes with sports catalytic converters, flap exhaust systems, duplex systems, etc. Since then, exhaust flap systems should no longer be present on new bikes, as they would reduce noise during the measurement test. The audit procedure has also been modified. However, the new regulations only apply to new vehicles. The fleet of older vehicles is not affected. That`s why your old bike may be noisier than your new purchase. The reason is simple: upgrading older machines would be inextricably expensive. You don`t want to expect pilots to do that.
If you are also looking for an acoustic shock absorber for your old machine, you will find the right parts in specialized stores. Also pay attention to the Swiss approval here! The car is one of the most popular means of transport. No other vehicle allows such freedom. In order to maintain functionality, it`s worth taking a look under the hood from time to time. This is where the heart of the vehicle with a combustion or electric engine is located. If it is dirty or provided with deposits, a surface engine wash is worth it. This ensures the continued functionality of the car. But be careful! Prior knowledge is required for an engine wash. Due to negligence, various components can easily be damaged. We answer the most important questions.
Too noisy – residents annoyed by JP Performance tuner The regulations are different and also depend on whether you drive a car or motorcycle. You can usually replace your vehicle`s components with genuine replacement parts. The Ordinance on Technical Requirements for Road Vehicles specifies the modifications and conversions permitted as part of the adjustment. However, this regulation is not lost in the details. If you`re not sure what you can change on your vehicle, help yourself: A small, high-speed landslide often causes costly damage. Even small scratches that seem harmless at first can lead to a lot of damage. A quirk on the windshield also endangers the safety of the driver, as the windshield serves to stiffen the body. If, for example, the windshield breaks while driving, this can have disastrous consequences.
Whether a repair is possible or whether the entire car window needs to be replaced depends on the type and location of the damage.
