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.\u003c\/p\u003e \u003cp\u003e\u003cbr\u003e\u003c\/p\u003e","brand":"K-Tuned","offers":[{"title":"304 - Polished Stainless Steel","offer_id":62764424429898,"sku":"KTD-KBH-421-501","price":491.88,"currency_code":"GBP","in_stock":true},{"title":"409 - Stainless Steel","offer_id":62764424462666,"sku":"KTD-KBH-421-409","price":354.9,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1059\/6116\/1034\/files\/k-tuned-4-2-1-swap-header-304-polished-stainless-steel-manifold-headers-174.webp?v=1784499788"},{"product_id":"speedfactory-titanium-exhaust-manifold-stud-kit-m10x1-25x54mm-honda-k-series","title":"Speedfactory Titanium Exhaust Manifold Stud Kit - M10x1.25x54mm - Honda K Series","description":"\u003cp\u003eEnhance the durability and performance of your Honda K Series exhaust manifold with the SpeedFactory Titanium Exhaust Manifold Stud Kit.

They keep the exhaust gases hot and when the exhaust is hot it moves out more quickly. So I bet your next question is, Does it make power ? The answer is yes. This header is definitely the top dog of K-Tuned swap headers. It beat both our K-Tuned 4-2-1 Swap header and even our 4-1Race header during dyno testing.

The K-Tuned RSX Header was designed with this exact theory in mind and utilizes a proven 4-2-1 Tri-Y design with extremely smooth slip fit merge transitions to increase the exhaust flow and power output of the Honda K engine. Like most Tri-Y designs, power gains are seen almost everywhere in the power band, not just the top end. Fitment is equally if not more important to us than function and although the subrame and swaybar on the RSX presented some design challenges, the final fitment was definitely worth some extra time. The secondary tubing passes perfectly through this tight area with extra clearance for engine movement.\u003cbr\u003e\u003cbr\u003eThe header features stepped piping beginning with 44mm primaries that progressively move into 48mm, then 50mm secondaries and finally a 64mm or 2.5\" exit. Like all our stainless headers, it is assembled with mandrel bent, 304 stainless steel tubing and is fully tig welded. We also use a slightly thicker gauge tubing that allows for better weld penetration and additional strength. The CNC cut 3\/8\" thick flanges are also double welded and then ported for optimum flow at entry and exit. This header directly replaces the OEM 2 piece design and eliminates the catalytic converter so we included a short 2.5\" test-pipe with defouler for the secondary O2 sensor.
