Product description

Not for cars with OEM muffler. Only for plain tube (Catalytic to Center muffler) or BES 997… muffler.

These headers and cats are perfect for those who want to run sport cats without a software program.

Our latest development for the GT3 is aimed at those who are looking for more torque in the mid range, a rich, deep exhaust growl and most importantly NO CHECK ENGINE LIGHT WITH STOCK SOFTWARE.

These headers contain the latest HJS cats, they 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.

By reducing the back pressure up to 20 (15kw) crank hp and 13 (15NM) crank torque.

Not for cars with OEM side mufflers
Manifold with 200 HD-catalysts
No DME program necessary
