The American Outlaw 2-into-1 system with its beefy 4 1/2" (114mm) diameter megaphone style muffler has a nostalgic yet powerful design and a real racing heritage. It will give any bike that sought-after deep roaring sound and is also packed with so many features, such as the one piece 2 1/2" (64mm) outer diameter 16 gauge heavy duty heat shields that cover the headers for a full 220 degrees and a three-step header system for performance. Systems come with a chrome or black ceramic coated finish and billet aluminum end cap. They also have removable baffles and Quiet baffles are separately available. All systems are equipped with O2 sensor ports and come with plugs for use on models without O2 sensors. These exhausts come complete and ready to bolt on and include stainless steel hardware and brackets.
