Product Description
  • Engineered and developed on the track, the GMG WC Long-Tube headers were designed to provide a consistent increase in power throughout the powerband. The design stems from our professional racing experience in running Porsche 3.8L and 4.0L engines throughout a broad spectrum of motorsports. While this header increases overall power output, it’s focus in the low and mid-range powerband.

    This header incorporates German-made HJS 200-Cell Metal-Matrix Sport Catalytic Converters. These dramatically cut down on obnoxious fumes inherent with race headers. HJS manufacturers the finest Catalytic Converters on the market today.

    Innovative Design - While the header features a Long-Tube unequal-length design, it is still modular with the rest of the exhaust system. This means you will be able to keep your sport button function if you are racing at a noise-restricted circuit.

    Fabrication - Each header is fabricated right here in Southern California. We use only the highest quality US-produced stainless steel tuning and laser-cut flanges. Each join is TIG welded and precisely normalized. The finished header features an exceptional finished and is peerless in its quality and durability.
