Walker Exhaust Exhaust Muffler P/N:21475
Walker Exhaust 18450 exhaust muffler for the 1993-1997 Nissan Altima 4-cylinder 2.4L quiets the exhaust as gases leave the engine. It is part of the SoundFX line of Walker Exhaust mufflers.
A muffler that is rusted through, rattles inside or leaves the exhaust louder than before may be worn out. A rattle or a louder exhaust note alone does not prove the muffler is at fault, since a cracked pipe or a loose hanger can make similar noise.
This is a direct-fit muffler for the 1993-1997 Nissan Altima 4-cylinder 2.4L.
