Exhaust system to open air — everything from the header back. Header-back systems are generally produced as aftermarket performance systems for cars without turbochargers. The Turbo-back (or turbo back) is the part of the exhaust system from the outlet of a turbocharger to the final vent to open air. Turbo-back systems are generally produced as aftermarket performance systems for cars with turbochargers. Some turbo-back (and header-back) systems replace stock catalytic converters with others having less flow restriction. Some systems (including in former time all systems) (sometimes nowadays called catless or de-cat) eliminate the catalytic converter. It is illegal and is against Federal
Exhaust brake the exhaust pipe. In this position the butterfly valve remains parallel to the path of exhaust gases and thus releases the pressure on the engine and allows its speed to increase. In this project, there is not a cylinder pressure mechanism but a simple linkage. A pedal brake is connected to the elastic rubber so that there will be pressure to apply and release butterfly valve like in an actual arrangement. A turbocharger is commonly used to improve power and reduce fuel consumption ratio. Study on effect of turbocharger on exhaust brake for diesel engines had practical significance. When butterfly
