Frequently Asked Questions

  1. Is this a direct fit for my vehicle?
    Yes. This Kooks component is engineered as a direct fit for the applications listed in the fitment table above. Verify your year, make, model, and engine against the fitment chart before ordering.
  2. What material is this product made from?
    Kooks performance exhaust components are manufactured from T304 aircraft grade stainless steel for superior corrosion resistance and long service life under high heat and performance conditions.
  3. Does this require professional installation?
    While installation can be performed by an experienced DIY mechanic with proper tools and a vehicle lift, professional installation is recommended. Improper installation can result in exhaust leaks, damage to oxygen sensors, or fitment issues.
  4. What warranty does Kooks provide?
    Kooks products are backed by a limited lifetime warranty to the original purchaser against defects in materials and workmanship. See the Kooks warranty documentation included with your product for complete terms and exclusions.
  5. Will this affect my factory warranty?
    Under the Magnuson-Moss Warranty Act, a manufacturer cannot void your vehicle's warranty simply because you installed an aftermarket part unless they demonstrate the aftermarket component directly caused the failure in question.
  6. Is a tune required after installation?
    A professional tune is recommended after installation of any performance exhaust component. Improved exhaust flow changes the engine's air fuel ratio and benefits from ECM recalibration to maximize power gains and ensure safe operation.
  7. Will this work with my stock exhaust system?
    Compatibility with the factory exhaust depends on the specific component. Long tube headers require connection pipes to mate with the cat back. Check the fitment details and connection specifications in the product listing above.
  8. How do I maintain this product?
    Kooks stainless steel components require minimal maintenance. Inspect all mounting hardware and connections after the first heat cycle and annually thereafter. Clean with stainless steel cleaner if discoloration occurs from heat exposure.

Install Instructions

Lift the vehicle and support it safely on jack stands. Allow the exhaust to cool fully before beginning removal of the factory components. Disconnect all oxygen sensor connectors before removing the factory manifolds or pipes. Install the Kooks headers using the provided hardware and gaskets, torquing in a cross pattern to specification. A professional tune is recommended after installation of long tube headers to maximize power gains and ensure proper air fuel ratios. Check all fasteners and connections after the first heat cycle.
