Muffler 3in

The Muffler 3in by WILLYS CARB is a compact exhaust silencer designed for builders and mechanics working on classic vehicles, hot rods, and custom automotive projects. This 3-inch muffler is essential for exhaust systems where space is limited or smaller displacement engines require effective sound suppression.

With a diameter of 3 inches, this muffler accommodates modest exhaust flow while maintaining effective sound dampening through its internal chamber architecture. Weighing 2.72 lbs, it is lightweight, making it ideal for builders focused on minimizing unsprung and rotating mass. The overall dimensions of 4.4 x 4.35 x 11.6 inches provide installation flexibility in tight engine bays or custom chassis builds.

This muffler is particularly suitable for mechanics upgrading small-displacement and mid-range carbureted engines, especially in British classics, early Jeeps, and compact hot rods where OEM mufflers may be unavailable or oversized. Ensure compatibility with your existing exhaust piping by verifying the 3-inch inlet/outlet specifications.
