And that leaves the muffler. The beauty of getting a new muffler
is that you can suit your taste: Some want whisper quiet and
others like a little rumble and some like a roar when they
cruise down our area highways.
Your exhaust system is more than a muffler. In some ways it
works like a chimney in your house, directing the byproducts of
burning fuel away from the people inside. The exhaust system
also controls noise and funnels the dangerous carbon monoxide
away from the passenger. Your exhaust system also incorporates
a catalytic converter which Is used to control harmful emissions
generated by the burning of fuel. The exhaust system also
provides a certain amount of back pressure that is required by
the engine to improve its fuel burning efficiency and increase
low RPM performance. Key components of your exhaust system
Designed specifically for each model, this pipe is used to
properly route exhaust to the back of the vehicle.
Acting like a funnel, the exhaust manifold collects the gases
from all cylinders and releases them through a single opening.
Some engines have two exhaust manifolds.
The catalytic converter reduces harmful emissions and transforms
pollutants into water vapor and other less harmful gases.
|WALKER?EXHAUST SYSTEMS: What is a Catalytic
The catalytic converter is designed to convert harmful
emissions, produced by an internal combustion engine, to
less-harmful elements: H2O (Water), CO2 (Carbon Dioxide)
and N2 (Nitrogen).
To perform this conversion, the catalytic converter works
with a vehicle's PCM (Powertrain Control Module) and other
emissions control devices.
OBDII (On-Board Diagnostics Version 2) monitors the
emissions control devices and provides feedback on their
As the EPA (Environmental Protection Agency) updates
emissions standards, the OBDII system becomes more
sensitive to fluctuations in emissions performance.
The muffler is a metal container with holes, baffles, and
chambers that reduces exhaust noise.
The resonator works with the muffler to reduce noise.
Found at the back of the car, the tail pipe carries exhaust
gases away from the vehicle.
