Modifying your vehicle with JDI products to improve off road performance may result in the vehicle handling differently than a factory equipped vehicle. Taller tires will cause the vehicle’s speedometer to read slow, so recalibration is required. Use of oversize tires, suspension lifts, body lifts, and other modifications may raise your vehicle’s center of gravity, resulting in an increased tendency for the vehicle to pitch and roll during sudden turns or abrupt maneuvering. Failure to drive with extreme care to prevent loss of control or vehicle roll over may result in injury or death. Drive at a reduced speed to ensure your ability to maintain control of the vehicle under all driving conditions. We recommend installing functional roll bars and cages as well as double shocking all vehicles for more safety and stability on or off road. Always wear seat belts when in a vehicle. Consult your owners manual for recommended tire sizes, safety instruction and warnings unique to your vehicle. It is your responsibility to check state and local laws restricting vehicle height to ensure that modifications to your vehicle are legal.

Exhaust Related Components

The regulation of emissions production, noise levels, and safety standards is undertaken by the federal government, each of the fifty state legislatures and by many local municipalities, towns and counties. California Vehicle Code Sections 27156 and 38391 prohibit the advertising, offering for sale, or installation of any device which modifies a vehicle’s emission control system unless exempted. James Duff headers have not received an exemption from these code sections and are not legal for sale or use in California on vehicles originally equipped with catalytic converters. It is illegal, except for vehicles only driven off-road, to remove or otherwise render inoperative any emission control device on regulated motor vehicles. In the other 49 states, it‑ is the responsibility of the ultimate consumer to check federal and local laws to determine if JDI products are legal for use on their vehicle.

Liability Disclaimer

JDI makes no warranties of merchantability, of fitness for a particular purpose, or that its products are approved for general use, or that its products comply with laws, regulations or ordinances in the states of the ultimate consumers. The entire risk as to the conformity of any product in any such state and as to repair should the product prove to be nonconforming, is on the ultimate consumer of such product and it is not upon JDI.

Without limiting the generality of the foregoing, JDI shall under no circumstances be liable for any incidental or consequential loss or damage whatsoever arising out of, or in any way relating to any such breach of warranty or claimed defect in, or nonperformance of the products. This warranty gives you specific legal rights and you may also have other rights which may vary from state to state. Some states do not allow limitations on how long an implied warranty lasts or do not allow the exclusion or limitation of incidental or consequential damages, so the above limitations and/or exclusions may not apply to you.
