m&m edition sport headers with 200 hjs hf sport cats

Our m&m edition headers and cats were created for those who have already purchased the FVD / m&m sport mufflers (either TUV or sound version). They are a logical progression for those looking for added mid range torque and top end horsepower. Combined with the FVD / m&m muffler they offer just as much power as the FVD / m&m complete exhaust system.

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.
