The major sources of pollution, the main constituents in exhaust gas pollution is nitric oxide (NO), carbon monoxide (CO), Carbon di-oxide (CO2), Sulphur di-oxide (SO2), & unburnt carbon particals.

Gas muffler helps running the vehicle quiet & silently therefore it is known as Silencer. In front of that silencer we are interested to join our accessories or equipment not only to reduce the noise but also to reduce the exhaust gases such as CO, CO2, SO2, NOx, & unburnt Carbon partical. All these gases are emitted out as smoke through exhaust pipe of vehicle, however the percentage of individual gases present in smoke varies according to various technical aspect such as formulation of air fuel mixture, its method of feeding in the combustion chamber.

We restrict ourself here only for nitric oxide (NO), carbon monoxide (CO), Carbon di-oxide (CO2), Sulphur di-oxide (SO2), & unburnt carbon particals.
