These individual pipes are available for customers who have our twin kit piping and need replacement parts or a different pipe after changing a turbo(s). Some customers use our piping to get them started in fabricating their own piping kits. Check with us if you have any questions on what to order. PLEASE NOTE that many parts are made to order, and may take a few days to ship. Also made-to-order parts are not returnable, although if you have an issue please contact us and we will always do what we can to help.
