200 cell hjs hd cats are also available. The latest hjs cats, are nicknamed ?hd? For high durability matrix design catalytic converters. They have a sm-matrix (winding of three flat and corrugated foils) and a special connection to the matrix sheath, which equates to extremely high durability for track and street use. The added benefit is that they do not generate catalytic efficiency codes (check engine light) that most OEM Porsche programs (eu 5 software) generate. Hd cats are perfect for those who want to run sport cats without a software program.
