Lexus TX350 Exhaust Pipe Replacement Cost

The exhaust pipe works like any other pipe, as it channels exhaust gas from one place to the next. It begins at the exhaust manifold flange, moves down to a specialty pipe called a 'flex pipe', and from there a new portion of the exhaust pipe extends from the flex pipe to the catalytic converter. This section of the pipe will contain an oxygen sensor, allowing the computer to analyze the exhaust before cleaning in the catalytic converter. After the catalytic converter, another section of exhaust pipe will move the cleaned exhaust to the muffler, and an oxygen sensor on that portion of the pipe will allow the computer to analyze the gases after cleaning. This provides a measurement of the efficiency of the catalytic convertor(s). Finally, the muffler is attached, and quiets down the noise from the engine. Attached to the muffler is the tail pipe, which channels the gas downwards, keeping heat away from the rear of the vehicle. This is a typical system, and there are many configurations of these parts.
