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
Intelligent Car Initiative Intelligent Car Initiative The Intelligent Car Initiative is a policy framework set up by the European Commission to tie up all activities relating to 'intelligent' automobiles. The term covers all vehicles that are equipped with modern information and communication technologies (ICT) to increase road safety and/or the flow of traffic, or to reduce the environmental impact of road transport.
