K-tuned 4-2-1 2.5'' Budget manifold stainless steel K-swap (Civic/CRX/Del sol/Integra)
90% of the products in our store are in internal or external stock and we can often process your order quickly (varying from a few hours to a number of business days).
Naturally it is possible that a product has an (unexpected) longer delivery time.
Upon receipt of your order, we will always inform you about this and offer any available alternatives. So keep a close eye on your mailbox.
We deliberately provide stock information about our products afterwards, because many suppliers do not offer a ''stock link system'' and we do not want to show '' estimates '' in advance, like many other webshops do (which are often incorrect and give you wrong information in advance). We only want to give our customers actual information on the moment of processing the order so we don't mislead our customers.
If you need a product VERY quickly and you need to be sure that we have it in stock, please e-mail or call us or send a message via ''ask a question about this product'' below in the product description.
The popular K-Tuned 4-2-1 Swap Header for K-series engine swaps is back again with some improvements. This header is capable of making very good power on relatively stock or mild engine setups. The main focus while designing our K-Tuned Swap Header was to blend excellent fitment, high quality construction and keep the price reasonable. We have upsized the primary piping slightly and improved the quality of all transitions to improve exhaust flow. The primary to secondary transition now uses an expanded secondary pipe at the joint to eliminate any restriction. The secondary pipes have also been changed a little and now merge together better at the collector. The header is constructed with 100% stainless steel with 3/8' thick flanges that are double welded and then ported for optimum flow. The piping is extra thick for added strength and to allow better weld penetration. These strength features add longevity and make a header that will be able to take the abuse of a firmly mounted K-swap engine. The strong interlocking flex-pipe can handle a lot of heat and has a 2.5' ID (Inside diameter). It flows very well and absorbs engine movement. Like our other headers, they are designed to fit most K-swap chassis perfectly. The header does not interfere with shifter mounting kits and is well centered in the exhaust tunnel. The 3-bolt exit flange prevents leaks and allows for installation to the existing exhaust piping with minimal modification. Please note that all of our headers will require some exhaust welding for installation.
Available in both stainless steel and 409 series steel
