What to Do About Exhaust Pipe Resonance?

[OGabrielle]

If the car's exhaust pipe exhibits resonance, it needs to be replaced immediately. Here is the relevant information: 1. The function of the car's exhaust pipe is to expel exhaust gases from the engine. The exhaust pipe consists of three sections: the header, the mid-pipe, and the tailpipe. The header is the exhaust manifold, the mid-pipe is the long tube under the chassis, and the tailpipe is the section near the rear bumper. 2. Modifying the mid-pipe and tailpipe of the exhaust can alter the sound but does not improve performance. The header of the exhaust pipe contains an important component—the catalytic converter—which reduces the levels of pollutants in the exhaust. Without the catalytic converter, the car's emissions would exceed standards, and the exhaust gases would emit a foul odor. 3. The exhaust manifold also has oxygen sensors—one in front of the catalytic converter and another behind the exhaust manifold.
