Many auto parts stores are sure to keep in their assortment numerous and varied muffler nozzles. You can buy any attachment for all popular brands and models of cars. And what is not on the counter can always be ordered from the catalog. The demand for such devices never subsides, unless, of course, the store is constantly updating the assortment.
The secret of the popularity of muffler attachments, first of all, is to improve the appearance of the car. Nondescript exhaust pipes after installing the nozzle give the impression that an expensive tuned exhaust system is installed on the car. In combination with other elements of the external body kit, the feed takes on a classic, exclusive or sporty look. Also, many nozzles alter the sound of the exhaust. Not all, but those that have a resonator in their design - a perforated insert that controls the sound of the muffler. At the request of the client, the car begins to sound lower and boomy, as if under the hood there is a powerful eight-cylinder unit, and not a standard subcompact engine. Or vice versa - the exhaust sound becomes high, like a Formula 1 racing car. However, changing the sound of a car does not mean changing its characteristics. The power of the engine or its torque does not increase, the environmental friendliness of exhaust gases does not decrease. Such advertising is often given to car accessories by unscrupulous sellers. In order for the parameters of the power unit to really improve, it is not a muffler attachment that is needed, but the replacement of the muffler itself with a sports muffler. But the nozzle can reduce the characteristics, but only slightly. By creating increased resistance to outgoing exhaust gases, they force the engine to spend additional energy to push them. So a fashionable attachment can get by with a power reduction of 1-2%. You can find adjustable resonator tips on sale. Such models allow the owner to change the sound of the muffler within a certain range. You can adjust the sound individually if the effect of other models for some reason did not satisfy someone. And you can change the sound every day depending on, for example, your mood. Motorcycle muffler attachments are another story. Two-stroke motorcycle, be sure to consult with experts. And not with sellers, but with engineers, technicians and dealership representatives. For two-stroke motorcycle engines, there are nozzles that slightly improve cylinder purging and, therefore, filling the cylinders with a fuel-air mixture. This can slightly increase power, reduce fuel consumption and wear of the cylinder-piston group. A positive effect is achieved only if the attachment is designed to work with a certain brand of two-stroke motor and is well manufactured.
