Land Rover Part Number: LR066423 - Rear Exhaust Muffler and Pipe
LR066423 is a rear exhaust muffler and pipe fitted to the rear exhaust system on Defender 90 wheelbase models. The assembly includes an integral silencer to reduce exhaust noise and routes combustion gases toward the vehicle tail. The unit combines the tail pipe and silencer in a single assembly, interfaces with underbody hangers and the connection flange, and on diesel models connects the mid-pipe or catalytic converter to the outlet behind the bumper. Routine inspection should check hangers, joints and the silencer body for corrosion or damage where exhaust leaks or excessive vibration can occur; replacement restores the intended exhaust routing and acoustic behaviour for the rear section of the system.
