Frequently Asked Questions

  • Q: Will this require tuning?
    A: Yes, custom ECU tune recommended to optimize air/fuel ratios and prevent check engine lights.
  • Q: Are these CARB legal?
    A: No, high-flow GREEN cats are for off-road/racing use and check local emissions laws.
  • Q: How much power will I gain?
    A: Significant increases in horsepower and torque, especially when paired with tune and exhaust.
  • Q: Do they include O2 sensor extensions?
    A: Yes, necessary extensions and hardware included for proper sensor placement.
  • Q: Do these Kooks headers require a tune after installation?
    A: Yes. A professional tune is strongly recommended after installing long tube headers. The significant improvement in exhaust flow changes air fuel ratios and requires ECM recalibration to achieve optimal power output and safe operation.
  • Q: Will Kooks headers void my factory powertrain warranty?
    A: Under the Magnuson-Moss Warranty Act, a manufacturer cannot void your vehicle warranty simply because you installed an aftermarket part unless they prove the component directly caused the failure in question. Consult your dealer for specifics.
  • Q: What warranty does Kooks provide?
    A: Kooks products are backed by a limited lifetime warranty to the original purchaser against defects in materials and workmanship. Racing and competition use applications may have specific warranty exclusions. Contact Kooks Performance directly for warranty details.
  • Q: How long does installation typically take?
    A: A typical Kooks long tube header installation takes 4 to 8 hours for an experienced mechanic with a vehicle lift. Tight clearances on specific platforms can extend install time. Always follow the included Kooks instruction sheet for your specific vehicle.
