Walker SoundFX Direct Fit Muffler for Chrysler and Dodge

Walker SoundFX Direct Fit muffler Part Number 18920 is a specific-fit exhaust muffler built for select Chrysler and Dodge center applications. It uses 100% aluminized steel for improved service life versus low-carbon steel and is shaped for a direct replacement on vehicles that call for a 2.5-inch inlet and 2.5-inch outlet.

  • Specific-fit exhaust muffler for direct replacement applications
  • Oval body shape with offset inlet and offset outlet configuration
  • 2.5-inch inlet inside diameter and 2.5-inch outlet outside diameter
  • Aluminized steel construction with aluminized finish
  • Mechanical interior joints and spun-locked heads for added durability
  • Combination muffler design for OE-style exhaust service
  • Walker SoundFX Direct Fit line focused on quality appearance and controlled acoustics

Product Details

Walker 18920 is part of the SoundFX Direct Fit product line, which is built for straightforward exhaust replacement where the original system uses a center-mounted muffler with offset pipe connections. The oval steel body measures 17 inches long, 11 inches wide, and 5.5 inches high, with an overall length of 21.75 inches. This muffler is intended for select 1998-2004 Dodge Intrepid, 1999-2004 Chrysler 300M, 1998-2004 Chrysler Concorde, and 1999-2001 Chrysler LHS center applications. This part cross-references AP Exhaust 700378 for the same application.

Common Exhaust Problems It Can Address

  • Rust-through or corrosion in the original muffler housing
  • Exhaust noise increase from a damaged internal muffler structure
  • Fitment issues when replacing a center muffler on a welded assembly
  • Loss of OE-style exhaust tone after the factory muffler deteriorates
  • Need for a direct-fit replacement with matching 2.5-inch pipe connections

Installation Notes

Compatible With 1999-2004 Chrysler 300M, center; 2002-2004 Chrysler Concorde, center; 1998-2004 Dodge Intrepid, center; and 1999-2001 Chrysler LHS, center. If the vehicle uses a welded assembly, replace all required parts; on some 1998-2001 Chrysler Concorde applications, modifications and/or additional parts may be required. Verify inlet and outlet offset orientation, pipe diameter, and center-position routing before installation. Walker 18920 is a direct-fit muffler, so matching the original exhaust layout is important for proper alignment.

Quality Assurance

Walker SoundFX Direct Fit mufflers are built with aluminized steel, mechanical interior joints, and spun-locked heads to support long-term exhaust service. The SoundFX Direct Fit line is engineered to provide a clean appearance and controlled acoustics for OE-style replacement work.
