When it comes to improving on an OEM design, this attention to detail and overall exhaust knowledge allows us to identify aspects of the factory parts that can be greatly improved upon. One of the first things to note about the OE exhaust manifold are the several points where flow is decreased due to a neckdown in piping diameter. These disruptions in exhaust flow result in decreased turbine efficiency which ultimately limits boost and power production. Furthermore, the OE merge collectors are made specifically with ease of manufacturing in mind and the result is a compromise on performance. The collectors contain very odd shapes that are bad for smooth exhaust flow and have several diameter restrictions that make them one of the biggest weaknesses of the stock manifold. Finally, the angle of the exhaust flow merge is also not ideal, causing the exhaust pulses to “fight” each other, which can add to flow differences for the twin scroll turbine, sacrificing spool and performance.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cspan\u003eAfter isolating the inadequacies of the OEM exhaust manifold, we were able to start identifying key areas of improvement: correctly sized and consistent exhaust runners that are more equal length, a consistent and non-bottlenecking merge collector inlet and outlet and a higher angle merge collector to direct flow into the turbine and prevent opposing flow disruptions. Beyond that, we decided on using thicker tubing and flanges for increased durability and longevity to more-effectively support the overhanging turbocharger.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cspan\u003eAll four of our exhaust runners are designed in conjunction with the merge collector to equal out the lengths as well as the overall bend angles. This is especially important in the FA WRX twin scroll turbine configuration because it makes the strength of each pulse, or “push” on the turbine wheel, at equal timing and consistency.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cspan\u003eSince the exhaust runners are CNC bent and trimmed as a single piece there are no additional welds to introduce points of failure or junctions that would interrupt flow, resulting an in impressive difference of less than 1% in total length. In addition, maximum variance is only 5 degrees from the most bent to the least bent runner, this mean we were able to produce what is a truly equal length, and equal bend manifold. The collector being cast, allows for the runner spacing and angles necessary to obtain the equal bends and lengths of all the tubes. This part is a major player in the GrimmSpeed manifold’s ability to fit between the stock skid plate and the oil pan while still providing the ideal performance from the rest of the design. The cast collector also allows for more smooth and consistent flow in the interior compared to a welded variant. This greatly simplifies the overall design, removing five more welded junctions, which could be a point for flow interruption or the structural failure that we see with other headers.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0743\/3165\/2402\/files\/headercloseup-banner_34bc2a4d-3cf0-4294-bef7-7ac730a8b828_1024x1024.jpg?v=1705437676\" alt=\"\"\u003e\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eThe head flanges of our header are CNC cut and faced from a 1\/2in thick piece of 304 stainless steel. This design is much thicker than OEM to increase reliability and longevity, as well as to provide additional material to be removed after welding to ensure flatness from flange to flange. This additional measure allows for greater gasket sealing which results in increased performance. The final touch is that the exhaust runners are welded inside the flange as well as outside, this is an extra step in manufacturing, but it provides a rounded lip to improve flow from the flange through the runner.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eAll of these things come together to make The GrimmSpeed 15-21 WRX Header not only the prettiest on the market, but also among the best performing and durable pieces you can purchase.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0743\/3165\/2402\/files\/headerheroshot_600x600.webp?v=1705437694\" alt=\"\"\u003e\u003c\/p\u003e\n\u003ch3 dir=\"ltr\"\u003eQUICK NOTES:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFull 304 Stainless Steel Construction –\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eFlanges, tubing, collector and badge\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrue Equal Length Runners –\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eCNC bent and trimmed, less than 1% variance from the longest to the shortest\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInnovative Cast Merge Collector –\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eLow restriction inlet and outlet, smooth flow and consistent performance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSmooth, Restriction-Free Flow Throughout –\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eSingle piece mandrel bent tubing welded to a single piece merge collector removes unwanted “steps”\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThick 1\/2in CNC Cut Flanges and 14ga Tubing –\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eAdded durability and longevity\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNo Tune Required –\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eSafe to run, just bolt on\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan\u003e\u003cstrong\u003eNo Ground Clearance Loss –\u003c\/strong\u003e Clears factory skid plate \u003c\/span\u003e\u003cspan\u003ewithout using spacers\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eJ-Pipe\/Turbo Bracket Included –\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eRetain the support that other aftermarket header lose\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGaskets and Hardware Included –\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eEverything you need to get installed and on the road\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufactured and Welded In The USA –\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eFor consistency and top quality control\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFITMENT:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003e2015-21 Subaru WRX\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e2014-18 Subaru Forester XT\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"GrimmSpeed","offers":[{"title":"Default Title","offer_id":39412833189990,"sku":"grm113008","price":979.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0075\/8703\/7237\/products\/grimmspeed-15-21-wrx-14-18-fxt-equal-length-exhaust-header-5789598.jpg?v=1786515619"},{"product_id":"tomei-unequal-length-exhaust-manifold-subaru-wrx-fa20dit-2015-2021-tb6010-sb04a","title":"Tomei [15-21 WRX] Unequal Length Exhaust Manifold FA20DIT  | TB6010-SB04A","description":"\u003cp\u003eYou want the rumble, we have you covered!  Part #: TB6010-SB04A\u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eThe OEM headers greatly restrict\u003cu\u003e \u003c\/u\u003eair flow right after the engine port.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003eUnlike the OEM headers, Tomei headers do not restrict air flow right after the engine port.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003eThe turbo side of the OEM headers severely restricts the flow of the exhaust gas, resulting in loss of power and efficiency.\u003cbr\u003e\u003cbr\u003eThe collector on the Tomei headers were made using the lost wax method.
