The exhaust system carries exhaust gases, treated by the catalytic converter, through a resonator, if applicable and into the exhaust muffler where exhaust noise is lessened. In order to secure the exhaust pipe to the exhaust manifold, a flange and seal-joint coupling is utilized. The exhaust system may utilize a slip-joint coupling design with a clamp and a U-bolt or a flange connection with a gasket. Exhaust hangers and rubber insulators help to support the weight of the exhaust pipe along with insulating any exhaust system vibration, rattle, or noise. Exhaust hangers also space the exhaust system away from the under-body of the vehicle and allows the exhaust system to expand as the exhaust system warms up. Exhaust heat shields are used to protect the body and other components from damage due to the heat from the exhaust system.
First Class Truck & Auto Service Inc can repair your exhaust system or if needed, completely replace the entire exhaust system on your vehicle.
The catalytic converter is an emission control device added to the engine exhaust system in order to reduce hydrocarbons (HC), carbon monoxide (CO), and oxides of nitrogen (NOx) pollutants from the exhaust gas. The catalytic converter is comprised of a ceramic monolith substrate, supported in insulation and housed within a sheet metal shell. The substrate may be wash-coated with 3 noble metals:
