Its compact design serves tight street-rod or custom-car spaces, using a single CNC-formed, laser-welded tube spun to a 4-inch round body around the catalyst. The range offers multiple connection sizes and center/center, angled/center and offset/offset layouts; proper ceramic catalyst loading supports airflow. California Legal is No. A heat shield is included, with no air tube.
