DynaFlex General Warranty Policy

Dynaflex Products are warranted for one year (1 yr.) from date of purchase with proof of purchase only.

Warranty Claims:
Dynaflex Products warrants the products or components parts sold conform to the specifications and physical descriptions contained in any or all Dynaflex Product literature, including but not limited to product catalogs, flyers or individual sale sheets. The Limited Warranty appearing on any or all Dynaflex Product literature is exclusive and is in lieu of all warranties whether written, oral or implied, including any warranty on fit or purpose.

Limited Warranty:
This warranty applies to and is for the benefit of the original purchaser only. If proof of purchase cannot be supplied, then the warranty will be from date of shipment, against defect in material and workmanship. This warranty does not apply if the defects are due to accident, neglect, corrosive environments or other abnormal service conditions.

Neglect, Corrosive Environments, and Abnormal Conditions:
If chrome is exposed to rock salt on snowy road conditions for extended periods of time it will corrode, crack, chip, and peel the chrome. Chrome needs to be cleaned intermittently to remove any corrosive materials. If your truck has an engine that is 2007+ the AK systems are the only systems Dynaflex Products can warrant. 07+ engines with a DPF will run very hot (1200 degrees), the AK system is the only product that can handle that heat. If you have on 07+ system that was factory fit with a DPF, but the DPF has been removed it will void your warranty for your chrome. 2007+ engines have engine programming that makes them burn rich, if you remove the DPF system, un-combusted Hydrocarbons will discolor and harm the chrome, Dynaflex Products is not responsible for holding warranty on trucks that changed from their OEM exhaust design. 2010+ exhaust systems contain selective catalytic reduction systems that use DEF (ammonia) to neutralize NOX. Ammonia is an environment contaminant and can discolor your chrome if not cleaned. SCR systems may let small amounts of aqueous ammonia out the tailpipe. Cleaning the tips of your tailpipes will ensure your chrome lasts. DPF/SCR systems that are improperly that improperly maintained may void your chrome warranty. DPF systems need to be cleaned every 1,000-1,500 operating hours. If not temperatures in your exhaust system may reach levels that chrome cannot withstand.

Systems:
Dynaflex Products innovated the 3 piece (Z-series) stack design and can only warrant complete z-series parts. We cannot warrant, for example, a Dynaflex Products elbow used with an import spool. We cannot guarantee the taper-loc joint will seal correctly if not using complete Dynaflex Products z-series kits with Dynaflex Clamps. This warranty is limited to the provisions shown and Dynaflex Products does not assume responsibility for the cost of removal or installation of the product or any consequential expense. Should the product appear to be defective within the warranty period, it should be returned to the dealer that the parts were purchased from. If their inspection confirms that the product failed as result of material or workmanship, and Dynaflex Products accepts responsibility the product will be replaced at no charge.
