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 heat recovery system used giving reduced emissions. This will also quicken cabin heating warm up for passenger comfort and window defrosting. For hybrid applications it also can warm the battery pack. The cooling system is connected to a heat exchanger placed in the exhaust gas transferring the thermal energy from the exhaust gas to the cooling system. When the engine is warmed up the exhaust gas is diverted to a by-pass pipe. Rankine cycle systems vaporize pressurised water using a steam generator located in the exhaust pipe. As a result of the heating by exhaust gases, the fluid is turned into steam. The
