Detailed Description

AP Exhaust 700378 is an exhaust muffler for center-position applications that require a direct-fit replacement with OE-style sound characteristics. The oval body, baffled muffler type, and pipe-style inlet and outlet support a factory-like exhaust path, while the aluminized steel body provides a practical balance of durability and value. This muffler is listed for 1998-2004 Chrysler Concorde, 1999-2004 Chrysler 300M, 1999-2001 Chrysler LHS, and 1998-2004 Dodge Intrepid, including 2002-2004 Chrysler Intrepid and 2002-2004 Dodge Intrepid. AP Exhaust 700378 is a fitment-focused choice for drivers replacing a welded OE muffler assembly on these Chrysler and Dodge sedans.

What It Helps Address

  • Exhaust noise that has increased from a worn muffler
  • Rust-through or corrosion in the muffler body
  • Factory exhaust tone that no longer matches OE levels
  • Replacement needs for welded OE-style center exhaust assemblies
  • Fitment issues when restoring a direct-fit Chrysler 300M or Dodge Intrepid exhaust section
