Walker Quiet-Flow 21374 Exhaust Muffler

Walker Quiet-Flow 21374 is a direct-fit exhaust muffler/resonator assembly built for OE-style sound and flow. It is engineered for front-position applications on select Chrysler, Dodge, and related models, including Chrysler 300M, Concorde, LHS, and Dodge Intrepid.

The Quiet-Flow line focuses on precise tuning and fitment, making this Walker 21374 a practical choice when you want a replacement that follows the original system layout and sound profile.

Key Features

  • Direct-fit exhaust muffler for select front-position applications
  • Oval resonator body with aluminized steel construction
  • Offset inlet and center outlet pipe connection layout
  • 2.25 in. inlet inside diameter and 2.5 in. outlet inside diameter
  • Walker Quiet-Flow tuning for OE-style exhaust sound and flow characteristics
  • Cross-reference: Hayden 2271

Product Details

Walker 21374 is designed around the original exhaust system geometry for vehicles that need a front-mounted muffler or resonator replacement. The oval body measures 16 in. long, 7.75 in. wide, and 3.25 in. high, with steel construction and an aluminized finish for corrosion resistance in everyday driving conditions. The offset inlet and center outlet configuration supports factory-style routing, while the Quiet-Flow design helps maintain the sound character expected from the original system.

Compatible With 1998-2004 Dodge Intrepid, front; 1998-2001 Chrysler Concorde, front; 1999-2004 Chrysler 300M, front; 1999-2001 Chrysler LHS, front; and 2002-2004 Chrysler Concorde, front. This part number, 21374, is a direct-fit option for drivers replacing a worn front exhaust muffler on these applications.

Common Replacement Reasons

  • Exhaust noise from a rusted or damaged muffler body
  • Loss of OE-style sound control after corrosion or internal failure
  • Fitment issues with a previous repair that does not match factory routing
  • Restricted exhaust flow caused by deterioration inside the resonator/muffler assembly
  • Need for a front exhaust replacement on Chrysler 300M, Concorde, LHS, or Dodge Intrepid

Installation Notes

Verify inlet and outlet orientation before installation, since this unit uses an offset inlet and center outlet layout. For welded assemblies, replace all required parts and confirm the surrounding exhaust sections are in serviceable condition. On some 1998-2001 Chrysler Concorde applications, modifications and/or additional parts may be required.

Quality Assurance

Walker Quiet-Flow products are tuned to fit, perform, and sound like the original system, using precise tuning technology to support OE-style exhaust characteristics. Part number 21374 is backed by a limited lifetime warranty on the listed applications.
