AP Exhaust Exhaust Muffler Assembly P/N:7317

Quiet your exhaust and keep gases flowing smoothly with the AP EXHAUST muffler assembly (MPN 7317). It installs as a direct-fit replacement for the 2007-2009 Nissan Altima [L4-2.5L], slotting into the exhaust system to dampen combustion noise as spent gases pass through.

• Aluminized steel construction: the muffler is built from aluminized steel for corrosion resistance against road moisture and exhaust condensation.
• Complete assembly: supplied as a muffler assembly to replace a rusted-through, rattling, or blown-out original.
• Made in the United States.

An exhaust muffler routes engine exhaust through internal chambers to reduce the sound of combustion before the gases exit the system. Signs the original may need replacing include a louder or droning exhaust note, a rattle from loose internal baffles, or visible rust and perforation in the muffler shell. If a failed muffler is the cause of your exhaust noise, this unit replaces it.
