Quiet the drone and route spent exhaust gases cleanly with the AP Exhaust muffler assembly (P/N 40001). It is a direct-fit replacement for the 2008-2012 Chevrolet Malibu with the L4-2.4L engine, dampening exhaust pulses so your Malibu runs at a normal, controlled sound level.
A muffler is the part of the exhaust system that reduces the noise created as combustion gases leave the engine, using internal chambers to absorb and cancel sound pressure. When the shell rusts through or the internal baffles break down, you'll typically hear a louder, raspy, or droning exhaust — signs this muffler may need replacing.
If a worn or rusted-out muffler is the cause of your excessive exhaust noise, this assembly replaces it.
