Engineered for significant power gains and an aggressive exhaust note, this system replaces your factory manifolds, catalytic converters, and H-pipe with superior components designed for optimal flow and durability.

Key Features for Enhanced Performance:

  • 1-7/8" Primary Tubes: Optimized for increased exhaust gas velocity and improved volumetric efficiency, leading to substantial horsepower and torque gains.

  • 3/8" Thick Flanges: Robust flanges ensure a secure, leak-free seal and long-term reliability.
  • 3" Slip-Fit Collectors: Designed for ease of installation and a precise fit, featuring merge spikes to further enhance exhaust flow.

Premium 304 Stainless Steel Construction

Built with TIG-welded 304 stainless steel, this system is designed for exceptional corrosion resistance and longevity. The flanges are a substantial 3/8" thick, providing a solid foundation for the entire assembly. This lifetime guaranteed, bolt-on system is engineered to connect seamlessly to the factory exhaust system, making installation straightforward.
