WARRANTY COVERAGE

Doug Thorley Headers header products are warranted against defective materials and workmanship for as long as the original consumer purchaser owns the product. Exhaust products, defined as components downstream of a Doug Thorley Headers product or an OE factory exhaust manifold, are warranted against defects in materials and workmanship for five (5) years from the original purchase date. These warranties are non-transferable and limited to the original purchaser.

Proof of purchase is required for all warranty claims. At our discretion, defective parts will be repaired, adjusted, or replaced. Authorized product returns will either be repaired or replaced, again at the discretion of Doug Thorley Headers.

Warranty coverage becomes void if the product shows evidence of unauthorized modifications such as mishandling, bending, welding, mutilation, or insulation wrapping. Doug Thorley Headers is not responsible for any expenses related to warranty claims, including labor costs or shipping fees.

Bluing and discoloration of chrome exhaust products and the dulling of ceramic-coated products are considered normal and are not covered under warranty. Likewise, environmental exposure and rust over the product's extended life are excluded from warranty coverage.

Any product discontinued from new sales for five (5) years or longer is no longer eligible for replacement. Only repairs will be offered for defective parts.

Non-defective, non-installed products may be returned within 30 calendar days of receipt and are subject to a 20% restocking fee.
