All products are made to order and require time to build "lead time" Orders can take up to 6 weeks to build. Any order canceled in this time frame will result in A 15% restocking fee. All orders and sales are final. We do not accept returns on exhaust products. If the product is defective you agree to let MBH Motorsports repair or replace it. Please limit your phone calls for order updates during the lead time stated above. All headers and downpipes come with a lifetime warranty accept if the header is coated or painted. Please be patient while we build you the best exhaust parts available. Refunds of orders will be made using the same payment method used to purchase. We do not refund shipping charges once the order has shipped.
