Refund policy

All products are made to order and require time to build (“lead time”). Orders can take up to 6 weeks to build.

Any USA-fabricated order canceled during this time frame is subject to a 15% restocking fee. All Flowsport series cancellations are subject to a 20% 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.

USA-made headers and downpipes come with a lifetime warranty, except where the header is coated or painted. Flowsport+ series products carry a 5-year limited warranty. See our Warranty Policy for full details.

Please limit phone calls for order updates during the lead time stated above. Please be patient while we build you the best exhaust parts available.

Refunds will be made using the same payment method used to purchase. We do not refund shipping charges once the order has shipped.
