Aftermarket exhaust parts restrictions in the system—can similarly increase performance, though would likely be illegal in areas where tampering with emissions devices is prohibited, particularly when placed in front of the catalytic converters. Aftermarket exhaust parts Aftermarket exhaust parts are intended to replace the factory fitted exhaust components of a car, motorcycle, or other motor vehicle in order to improve the performance, visual appeal, or sound of the vehicle. Generally, performance enhancements are achieved by reducing the back pressure of the factory exhaust system. Frequently a side effect of a free-flowing exhaust system is either a "different" sound, a higher noise level, or
Emily Vanhoutte this because exhaust gases are the main sources of air pollution. Actually, many people are exposed to exhaust emissions every day in different ways: motor vehicles running on fuel and diesel, trains, ships, electric generators, factories and plants. When you take the bike and leave your car at home you reduce the air pollution and save our planet. 4. I did a campaign to promote windmills. A windmill is a machine that converts the energy of wind. Green energy is important to save the health of our planet. Clean electricity generated from the wind is important for our future but
