FancyTark Lawn Mower Muffler Exhaust 1-3/8" Inlet/Outlet, Powder-Coated Steel, Welded Seams

FancyTark replacement muffler exhaust for lawn mowers with 1-3/8" inlet and outlet provides a direct-fit, heavy-gauge steel exhaust that redirects gases and resists corrosion.

If your mower uses Cub Cadet or compatible Kohler systems and the original muffler has cracked, rusted, or become noisy, this FancyTark unit is designed as a practical, durable replacement. It matches several OEM reference numbers (393840-R91, IH-393840-R91, 237550-S, 237550, 105-296) and fits engines specifying a 1-3/8" inlet and outlet diameter. The powder-coated steel body and welded seams improve longevity while the integrated bracket helps secure the part to the mower chassis.

How does this muffler protect the engine and reduce noise?

The unit directs exhaust away from the engine and critical components while providing a barrier to heat and debris. Although not a soundproofing guarantee, its construction helps control exhaust flow and reduces vibration-transferred noise relative to damaged or corroded originals.
