In a nutshell, we opted for a cast manufacturing method because it reduced the chance of failure modes, reduced the overall size and weight, and gave us more flexibility in design.&nbsp;&nbsp;<\/p>\n\n\n\n<p>Like most <a href=\"https:\/\/corksport.com\/blog\/mazdaspeed-3-exhaust-manifold-break-down\/\" title=\"Mazdaspeed 3 Exhaust Manifold Break Down\">exhaust manifolds<\/a>, we opted to use 304 stainless steel because it is corrosion-resistant, handles heat well, and is a common and cost-effective material.&nbsp;&nbsp;<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/corksport.com\/blog\/\"><img loading=\"lazy\" decoding=\"async\" width=\"800\" height=\"784\" src=\"https:\/\/cloudfront.corksport.com\/blog\/wp-content\/uploads\/2020\/06\/mazdaspeed-turbo-manifold-cad-model.jpg\" alt=\"Mazdaspeed Cast Exhaust Manifold modling in CAD\" class=\"wp-image-12015\" srcset=\"https:\/\/corksport.com\/blog\/wp-content\/uploads\/2020\/06\/mazdaspeed-turbo-manifold-cad-model.jpg 800w, https:\/\/corksport.com\/blog\/wp-content\/uploads\/2020\/06\/mazdaspeed-turbo-manifold-cad-model-300x294.jpg 300w, https:\/\/corksport.com\/blog\/wp-content\/uploads\/2020\/06\/mazdaspeed-turbo-manifold-cad-model-768x753.jpg 768w\" sizes=\"(max-width: 767px) 89vw, (max-width: 1000px) 54vw, (max-width: 1071px) 543px, 580px\" \/><\/a><figcaption class=\"wp-element-caption\">Check out our other Blogs<\/figcaption><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">Following up is the Design of The Exhaust Manifold<\/h2>\n\n\n\n<p>The list of details that went into the design is far too long to list here, but we can cover the major items that define the CS Exhaust Mani. With investment casting, we had a lot more flexibility in design with the bend radius, diameters, and wall thickness of the individual runners. This allowed us to increase the inner diameter of the runners to 1.59 inches, achieve a 0.200-inch wall thickness, and fine-tune the path and bends of each runner to optimize runner length and flow.&nbsp;&nbsp;<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/corksport.com\/blog\/\"><img loading=\"lazy\" decoding=\"async\" width=\"800\" height=\"695\" src=\"https:\/\/cloudfront.corksport.com\/blog\/wp-content\/uploads\/2020\/06\/corksport-exhaust-manifold-flow-simulation.jpg\" alt=\"Mazdaspeed Cast Exhaust Manifold airflow modling\" class=\"wp-image-12016\" srcset=\"https:\/\/corksport.com\/blog\/wp-content\/uploads\/2020\/06\/corksport-exhaust-manifold-flow-simulation.jpg 800w, https:\/\/corksport.com\/blog\/wp-content\/uploads\/2020\/06\/corksport-exhaust-manifold-flow-simulation-300x261.jpg 300w, https:\/\/corksport.com\/blog\/wp-content\/uploads\/2020\/06\/corksport-exhaust-manifold-flow-simulation-768x667.jpg 768w\" sizes=\"(max-width: 767px) 89vw, (max-width: 1000px) 54vw, (max-width: 1071px) 543px, 580px\" \/><\/a><figcaption class=\"wp-element-caption\">Check out our other Blogs<\/figcaption><\/figure>\n\n\n\n<p>With that flexibility in design, we were able to increase peak flow and improve flow balance per runner. Overall we were able to increase peak flow 45% over the OEM manifold and 33% over the XS Power V3.&nbsp;&nbsp;<\/p>\n\n\n\n<p>Next up in design, and arguably the most exciting and unique aspect, is the modular flange system.&nbsp;&nbsp;<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/corksport.com\/mazdaspeed-exhaust-manifold.html\"><img loading=\"lazy\" decoding=\"async\" width=\"800\" height=\"535\" src=\"https:\/\/cloudfront.corksport.com\/blog\/wp-content\/uploads\/2020\/06\/mazdaspeed-t3-exhaust-manifold.jpg\" alt=\"Mazdaspeed Cast Exhaust Manifold modular flange system\" class=\"wp-image-12017\" srcset=\"https:\/\/corksport.com\/blog\/wp-content\/uploads\/2020\/06\/mazdaspeed-t3-exhaust-manifold.jpg 800w, https:\/\/corksport.com\/blog\/wp-content\/uploads\/2020\/06\/mazdaspeed-t3-exhaust-manifold-300x201.jpg 300w, https:\/\/corksport.com\/blog\/wp-content\/uploads\/2020\/06\/mazdaspeed-t3-exhaust-manifold-768x514.jpg 768w\" sizes=\"(max-width: 767px) 89vw, (max-width: 1000px) 54vw, (max-width: 1071px) 543px, 580px\" \/><\/a><figcaption class=\"wp-element-caption\"><em>Mazdaspeed Exhaust Manifold<\/em><\/figcaption><\/figure>\n\n\n\n<p>This is unlike any other manifold available for the Mazdaspeed today\u2026you can choose your flange between OEM Stock Flange, Precision V-Band, or T3. Sure all these options are available today from other options, but none are modular. Say you pull the trigger on the OE Stock Flange today, but a year from now you want to upgrade your build to a Precision V-band flange. With any other manifold, you would have to buy another $900+ manifold to get the new flange, but with the CorkSport Exhaust Manifold, you just have to get the new flange elbow for your setup. This is MUCH MUCH cheaper and easier to change!<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/corksport.com\/\"><img loading=\"lazy\" decoding=\"async\" width=\"800\" height=\"600\" src=\"https:\/\/cloudfront.corksport.com\/blog\/wp-content\/uploads\/2020\/06\/corksport-stainless-steel-exhaust-manifold.jpg\" alt=\"Installed Mazdaspeed Cast Exhaust Manifold \" class=\"wp-image-12019\" srcset=\"https:\/\/corksport.com\/blog\/wp-content\/uploads\/2020\/06\/corksport-stainless-steel-exhaust-manifold.jpg 800w, https:\/\/corksport.com\/blog\/wp-content\/uploads\/2020\/06\/corksport-stainless-steel-exhaust-manifold-300x225.jpg 300w, https:\/\/corksport.com\/blog\/wp-content\/uploads\/2020\/06\/corksport-stainless-steel-exhaust-manifold-768x576.jpg 768w\" sizes=\"(max-width: 767px) 89vw, (max-width: 1000px) 54vw, (max-width: 1071px) 543px, 580px\" \/><\/a><figcaption class=\"wp-element-caption\">CorkSport<\/figcaption><\/figure>\n\n\n\n<p>Speaking of install, compared to the typical performance exhaust manifold the CS design is cake to install. With the modular design, you are not fighting the entire bulk for the manifold and flange at the same time. You can leave you turbocharger unmoved connected to the downpipe and intake system, you just install the flange elbow after the manifold is in and bolted to the engine.&nbsp;&nbsp;<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/corksport.com\/mazdaspeed-exhaust-manifold.html\"><img loading=\"lazy\" decoding=\"async\" width=\"800\" height=\"450\" src=\"https:\/\/cloudfront.corksport.com\/blog\/wp-content\/uploads\/2020\/06\/Corksport-exhaust-manifold-mazdaspeed.jpg\" alt=\"Full product Mazdaspeed Cast Exhaust Manifold\" class=\"wp-image-12020\" srcset=\"https:\/\/corksport.com\/blog\/wp-content\/uploads\/2020\/06\/Corksport-exhaust-manifold-mazdaspeed.jpg 800w, https:\/\/corksport.com\/blog\/wp-content\/uploads\/2020\/06\/Corksport-exhaust-manifold-mazdaspeed-300x169.jpg 300w, https:\/\/corksport.com\/blog\/wp-content\/uploads\/2020\/06\/Corksport-exhaust-manifold-mazdaspeed-768x432.jpg 768w\" sizes=\"(max-width: 767px) 89vw, (max-width: 1000px) 54vw, (max-width: 1071px) 543px, 580px\" \/><\/a><figcaption class=\"wp-element-caption\"><em>Mazdaspeed Exhaust Manifold<\/em><\/figcaption><\/figure>\n\n\n\n<p>Making life even easier\u2026we opted to develop a pre-fabbed dump tube (screamer pipe) for the Tial 44mm EWG. This is an optional feature for the kit, but one we highly suggest because it\u2019s just so damned easy. Designed for <a href=\"https:\/\/corksport.com\/mazdaspeed-3\/\">MPS 3<\/a> and <a href=\"https:\/\/corksport.com\/mazdaspeed-6\/\">MPS 6<\/a>, it fits around most standard downpipes and dumps below the sub-frame right behind the drive axle.

We did not want to lose that so we did our best to hit performance goals without sacrificing the Mazdaspeed grumble.&nbsp;&nbsp;<\/p>\n\n\n\n<p>One of our Beta testers put together a great video comparing the sound of OEM vs CorkSport.

Either way, the grumble lives on, and honestly, none of our beta testers can stop grinning ear to ear with every WOT pull.&nbsp;&nbsp;<\/p>\n\n\n\n<p>With that being said act fast!
