Kerker exhausts are completely re-buildable and are finished in brilliant triple-nickel chrome plating. This classical looking SE Series 2-into-1 system for Softail comes without muffler end cap. This allows you to change the appearance of this exhaust to match with the styling of your bike. For example the classic FishTail end cap for that vintage look, or the tapered end cap for a stock appearance. The Turndown caps can be positioned in one of three positions, depending on your bike's equipment. And that are just three of the 17 available end caps. SE series 4" diameter end caps are sold each and listed separately.
