Typically made of cast iron or fabricated tubing, it sometimes incorporates the catalyst, and is connected to the engine at the exhaust ports with flange connectors. It is designed to collect exhaust gases from each cylinder, then funnel them into a common outlet.
Allows normal engine movement to prevent damage to the exhaust system.
Converts harmful engine emissions to CO2 and water.
Detect the level of O2 in the exhaust stream. This information is utilized by the PCM for fuel control, and to monitor converter efficiency.
Required accessories for proper sealing and durability.
Resonator assemblies combine pipe routing and tuning technologies for quality flow and acoustics.
The muffler quiets the sound of a vehicle's engine as emissions pass out of the exhaust system.
