H2 exhaust is a very important aspect of the H2 as it is for any other vehicle. The exhaust system is responsible for getting rid of various small particles created by incomplete combustion of fuel in the engine. The exhaust created with internal combustion engines is toxic and/or noxious and must be dealt with properly.
If internal combustion engines operated at 100 percent efficiency, exhaust systems would not be needed. Every vehicle created comes equipped with a system designed to combust the remaining particles that make it through the internal combustion engine in order to keep these harmful particles from entering the atmosphere. Another aspect of the exhaust is the muffler, which limits the amount of noise released from the combustion process.
When choosing a new H2 exhaust system, you can choose a system that limits the sound of the engine at different degrees. Mufflers are designed to allow certain levels of sound to emit from them. Inside each muffler is a set of tubes with holes in them to deflect and redirect sound within the muffler housing. Sound waves bounce around inside the muffler canceling each other out while some sound escapes.
H2 exhaust mufflers can be designed to cancel out a small or large percentage of the sound waves created by the vehicle. This allows you to have a quiet vehicle or one that growls down the road. The only catch is, once you have made up your mind and installed the muffler you desire, you cannot change its sound levels without replacing the unit, so choose carefully.
