Product Details

Walker Quiet-Flow is Walker’s OE-style replacement line focused on precision fit, steady exhaust flow, and sound characteristics that stay close to original equipment. For the 1984-1989 Nissan 300ZX, Part Number 55135 is shaped as a combination muffler assembly with a round 7-inch body diameter, 7-inch body height, and 7-inch body width. The offset inlet and outlet layout helps match the factory exhaust path, while the dual-tip outlet configuration supports the original rear-exit appearance.

This part cross-references Anchor 3213 and Gates 28211 for the same application. If you are searching for a Walker 55135 muffler assembly for Nissan 300ZX exhaust repair, this OE-style replacement is built around the listed dimensions and fitment data for the 1984-1989 model years.

Common Problems It Can Address

  • Rust or corrosion in the original muffler body
  • Exhaust noise caused by a worn or damaged muffler
  • Poor fitment after previous exhaust repairs
  • Restricted exhaust flow from an aging muffler assembly
  • Loss of factory-style exhaust routing on a Nissan 300ZX

Installation Notes and Tips

Verify inlet and outlet diameters, offset configuration, and overall length against the existing exhaust before installation. Because this is a pipe-connection muffler assembly, proper alignment of the inlet and dual-tip outlet is important for a clean fit on the 1984-1989 Nissan 300ZX. Confirm the vehicle’s exhaust layout and mounting points before final assembly.
