A longer round muffler for your custom exhaust

Choose a round muffler that fits the pipe size and space in your project. Kooks R300-14-CI has a polished 304 stainless body, 3-inch inside-diameter joints and a 14-inch body length.

SKU: R300-14-CI

Allow for the complete length

The full muffler is 20 inches long, with a 4-1/2-inch outside-diameter body. Those are the dimensions to check around the floor, chassis and connecting pipes.

The slip-fit clamps are included

The inlet and outlet slip over 3-inch outside-diameter tubing, with two JI-TAS300 clamps supplied. Welding is not required for the specified clamp-in installation. Each item is one muffler.

Matching products

For less mounting length in a custom 3-inch exhaust, the 10-inch-body round muffler has the same 4-1/2-inch outside body diameter and a 15-1/2-inch overall length; it is a separate single-muffler choice.
