Unlock the true potential of your VQ-powered Nissan or Infiniti with the SPDZ1 HGC (High Ground Clearance) Long Tube Headers. Engineered for enthusiasts who demand maximum performance without sacrificing drivability, these headers deliver noticeable horsepower gains, stronger mid-range torque, and an aggressive exhaust note that every VQ owner loves.
Unlike conventional long tube headers, the innovative High Ground Clearance (HGC) collector design tucks the collectors higher into the chassis, dramatically improving ground clearance while maintaining excellent exhaust flow. The stepped primary design helps preserve low and mid-range torque while still supporting impressive top-end power gains.
Manufactured from premium 304 brushed stainless steel with heavy-duty CNC-machined flanges, these headers are built to withstand years of abuse on both street and track.
