OE-Style Exhaust Muffler Assembly

Walker Quiet-Flow 70003 is a direct-fit exhaust muffler assembly built for a precision OE-style replacement. It is engineered for controlled exhaust flow and OE-style sound, with aluminized steel construction for added corrosion resistance.

  • Direct-fit muffler assembly for a clean replacement path
  • Aluminized steel construction for improved durability
  • Oval combination muffler design with offset inlet and outlet
  • Pipe connection inlet and tip outlet for application-specific fitment
  • Walker Quiet-Flow 70003 supports a factory-style exhaust repair

Fitment Details

Compatible with 2009-2014 Acura TSX, right side. This fitment covers the Acura TSX application listed for the right-side position, making Walker 70003 a targeted replacement for the specified exhaust configuration. The muffler’s 2.25-inch inlet size, 54.75-inch overall length, and oval steel body help match the original layout while maintaining OE-style sound characteristics.

The Quiet-Flow product line focuses on direct-fit exhaust replacement with coverage for domestic and foreign vehicles. For buyers searching for an Acura TSX muffler assembly or Walker 70003 exhaust muffler assembly, this part is positioned as an OE-style solution rather than a universal component.

What It Helps Address

  • Exhaust noise that has increased due to muffler wear
  • Corrosion-related muffler deterioration
  • Fitment issues from a damaged or mismatched exhaust assembly
  • Loss of factory-style exhaust tone after repair

Installation Notes

Verify inlet and outlet configuration, body dimensions, and right-side fitment before installation. This assembly uses a pipe connection inlet and tip outlet, so matching the existing exhaust layout is important for proper installation. If the original system uses a welded assembly, replace all required related parts as specified for the application.

Quality Assurance

Walker Quiet-Flow 70003 is part of Walker’s OE-style replacement line and is built for precision fit and controlled exhaust flow. Part number 70003 is also cross-referenced to 93131 and OSC 30044 for the same application.
