Will my order ship out if one of the items are out of stock?
Your order will be on hold until we receive every item in stock for shipping your order out complete.
Which gaskets will I need for my headers?
Header purchases will include a graphite paper gasket. We recommend upgrading to the GM multi-layer steel gaskets for all header installs.
Do I need spark plug wires and what length would I need for my application?
Our headers do require an aftermarket spark plug wire for completing installation. Due to the larger primary tube and the routing of the tubes, we recommend wires with a 45-degree boot, such as our house brand. We also offer an MSD set with an adjustable boot. The length of the wire set needed would be based on your factory wire length, measured from boot end to boot end.
What is your exchange/return policy?
We accept returns within 30 days of the delivery date. All returns must be in new, unused and resalable condition with no bolt marks or scratches and are subject to a 20% restocking fee.
Headers will NOT be accepted if the engine has been started or the vehicle has been driven.
Headers cannot be returned if the engine has been started or the vehicle driven.
If you would like to exchange them for a different item, we do not charge a restocking fee on the returned item. Include in the box a copy of your invoice with a memo of whether you would like a return or exchange. Please include your contact information for any exchanges. Then ship the returning item back to us. When we receive and process the returned item, we will contact you about the exchange and any applicable payment and shipping charges.
Do you ship in California?
Unfortunately, we are restricted/unable to sell or ship any of our exhaust or other emission-based items in the state of California due to CARB and EPA laws. This applies to retail and wholesale accounts. That includes any orders in person, over the phone, website, amazon, and eBay. We are sorry for any inconvenience.
Do you ship Internationally?
We only offer international shipping through eBay’s global ship program and not through our own website. You would need to place your order through our eBay store to ship the items internationally. We are unable to see your international shipping cost, taxes, duties, etc., but eBay should be able to provide an appropriate shipping quote. Unfortunately, not all our products will be listed on eBay. Another option would be to use a freight forwarding company inside the USA with a non-California address.
