Paint Warning:
These headers are painted with a high heat dull black paint. It will generally dull even more when the engine is started. The header paint will smoke and let off an odor the first few times the engine is up to temperature and the black finish will become duller turning closer to gray in color. If exhaust temperatures are extreme at start the paint will blister and peel. There is no warranty on header paint.
Header Return Policy:
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.
