Product Details

The 22566 muffler is a regular-grade, steel-bodied unit with an 8.38-inch body width and height, 29-inch body length, and 38.75-inch overall length. Its offset inlet and outlet configuration helps it work in exhaust layouts that require a compact, serviceable replacement muffler. This part cross-references CSF 3719 for the same application.

It is also a practical choice when replacing a worn muffler on vehicles such as Ford F-250 and Chevrolet Silverado applications that use a 3-inch exhaust connection and offset routing.

Common Problems It Can Help Address

  • Excessive exhaust noise from a damaged muffler
  • Restricted exhaust flow caused by internal muffler deterioration
  • Corrosion-related muffler failure in steel exhaust systems
  • Fitment issues when replacing an offset, flange-style muffler
  • Service needs on commercial or on/off-road exhaust systems

Installation Notes and Tips

Verify inlet and outlet orientation, flange style, and 3-inch connection sizing before installation. Because this is a universal muffler, confirm available space for the 38.75-inch overall length and the 29-inch body length, along with the offset inlet and outlet layout. Professional exhaust installation is recommended to ensure proper alignment and sealing.
