Polished Stainless Steel Warning:
Stainless header tubing when exposed to exhaust temperature will cause the finish to change color which will vary with the exhaust temperatures. Please note that the finish of the header when the engine is started will change to a light champagne color to a darker gold finish and in some instance may even turn dark blue or purple. This can be polished out when utilizing Blue-away or Simi-chrome polish, but please note that when the headers reach running temperature, they may change color again. No warranty or returns on polished stainless steel exhaust items once they have been installed.
Header Return Policy:
Please refer to the header measurement chart below to make sure the header will fit your vehicle and application before ordering. In the event you order a header that will not fit your vehicle and application, you may return them for a refund, providing you don't damage the header. When you receive the header the finish will be protected and must remain unscratched for a refund. If you bend or dimple any of the tubes or scratch the finish, we will not be able to sell the header and will not be able to process a refund. Use care when trial fitting headers. Repack them well to prevent damage returning them to us. We won't process refunds for scratched, dimpled, dented, or bent headers.
