Quiet your exhaust and keep gases flowing smoothly with the AP Exhaust muffler assembly (MPN 7511). It drops in as a direct-fit replacement for the 1999-2003 Lexus RX300 [V6-3.0L], taking the place of a factory muffler that has rusted through or blown out.
A muffler dampens the sound pulses of the exhaust stream as they exit the engine, lowering noise while allowing spent gases to pass to the tailpipe. Signs this part may need replacing include a louder or droning exhaust note, a rattle from a broken internal baffle, or visible rust and perforation in the muffler shell. If a failed muffler is the cause of your excessive exhaust noise, this assembly replaces it.
