This up-pipe makes for an excellent exhaust upgrade as the factory up-pipe can rob you of power and performance. Over time and mileage, and several heat cycles, the insides of the factory downpipe can break apart which can block the flow path of the turbocharger. This can make your vehicle feel weak and down on power, while your turbocharger works harder to reach boost levels that fall short of your factory settings. This can also cause premature wear to your turbocharger while creating an excessive amount of heat from the factory up-pipe. Invidia relieves this issue with their up pipe as it has been designed with a smooth bend to allow for unobstructed exhaust flow starting right at the turbocharger. This will allow for a better turbo response which will also create more horsepower and more torque.\u003c\/p\u003e","brand":"Invidia","offers":[{"title":"Default Title","offer_id":45765804196129,"sku":"INVHS02SW1UPP","price":261.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/9029\/2257\/products\/1592733f42d9ba49ede71711647d928c.jpg?v=1697907763"},{"product_id":"kil-hh-diy-killer-b-motorsport-4-1-holy-header-diy-rotated","title":"Killer B Motorsport 4-1 Holy Header DIY Rotated - Subaru Models (inc. 2002-2014 WRX \/ 2004-2021 STI)","description":"Symmetrical 4-1 design maintains high and consistent exhaust velocity as RPMs rise.

A tune is not optional with this installation — running any aftermarket downpipe on the stock ECU calibration is a reliability concern, not just a performance one.\u003c\/p\u003e\n\n\u003ch4\u003e\u003cstrong\u003eWhat's Included\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eInvidia Catted Downpipe with Divorced Wastegate\u003c\/li\u003e\n  \u003cli\u003eHigh-flow catalytic converter\u003c\/li\u003e\n  \u003cli\u003eNew exhaust gasket and hardware\u003c\/li\u003e\n  \u003cli\u003eNOTE: Does not include turbo-to-downpipe gasket — source separately\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch4\u003e\u003cstrong\u003eAbout Invidia\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cp\u003eInvidia is a Taiwanese performance exhaust manufacturer with a strong following in the Subaru, Mitsubishi, and Japanese sports car communities.

All of the bends utilize a mandrel for smooth non-restrictive flow. Not only that, they use the largest bends possible at every location.

Would 304 stainless work, yes, but the temperatures on turbocharged cars can exceed the limits of 304 stainless enough to make them brittle and crack. 321 stainless steel has higher strength and toughness at elevated temperatures. It was developed by the aircraft industry specifically to address 304 stainless manifolds that were cracking. Killer B Motorsport is the only company that manufactures full 321 headers. \u003c\/li\u003e\r\n\u003cli\u003eHigh Heat Retention. 321 stainless steel conducts less heat than 304 stainless steel. The short primaries and properly sized secondary’s also pull less heat from the exhaust gasses increasing turbine efficiency. Large tubing headers expose the exhaust gasses to more surface area transmitting more heat and reducing exhaust energy.

Would 304 stainless work, yes, but the temperatures on turbocharged cars can exceed the limits of 304 stainless enough to make them brittle and crack. 321 stainless steel has higher strength and toughness at elevated temperatures.

The short primaries and properly sized secondary’s also pull less heat from the exhaust gasses increasing turbine efficiency. Large tubing headers expose the exhaust gasses to more surface area transmitting more heat and reducing exhaust energy.

Invidia made the 2015-2021 Subaru STI downpipe from mandrel bent 3\" stainless steel and welded on a thick flange and a cast stainless steel housing to provide maximum airflow and improved performance. A divorced wastegate downpipe has a plate that protrudes into the turbo to separate exhaust flow coming out of the turbo to reduce turbulence. This is optimal for stock and smaller-sized turbo upgrades. The high-flow catted Invidia STI downpipe is not emissions legal, and may still cause a CEL in some cases. The high-flow catted downpipe also helps to reduce boost spike by adding back pressure to the turbo system.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSuperior Design\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe factory downpipe is highly restrictive by the nature of the design and begins right after the turbocharger leaving much room for improvement.

These gaskets feature durable multi-layer stainless steel construction to provide you with an optimal seal.

Because of these reasons, anytime you remove your exhaust for upgrades or maintenance the existing gaskets can come apart or become brittle. You should always use new gaskets upon re-assembly, or at the least, thoroughly inspect your gaskets as the exhaust manifold can be a labor-intensive job, you would not want to get everything back together to learn about an exhaust leak upon startup.

This with smooth bends as much as possible within the manifold design will allow for an unobstructed flow path for the exhaust to exhale the exhaust gases as proficient as possible for those with moderate bolt-ons.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch4\u003e\u003cstrong\u003eNOTE:\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003e02-05 wrx requires 2.5l sti oil pan (on some)\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003e06-07 wrx requires sti oil cooler and sti oil pan\u003c\/strong\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"Invidia","offers":[{"title":"Default Title","offer_id":45763371761953,"sku":"INVHS05SW1HDP","price":1820.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/9029\/2257\/products\/3165cab81ce9e473eae91a8342f89d5e.jpg?v=1697903160"},{"product_id":"invidia-n1-dual-exit-cat-back-exhaust-titanium-tips-2008-2014-subaru-wrx-hatchback-2011-2014-subaru-sti-hatchback","title":"Invidia N1 Dual Exit Cat Back Exhaust - Titanium Tips - 2008-2014 Subaru STI Hatchback \/ 2011-2014 WRX Hatchback","description":"\u003ch4\u003e\u003cstrong\u003eThe N1 Dual Exit: The Boxer Sound From Both Sides\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cp\u003eThe Invidia N1 Dual Exit Cat-Back Exhaust with Titanium Tips for the 2008-2014 Subaru WRX \/ STI runs twin exits at the rear of the car — two Titanium tips giving the GR WRX\/STI a wider, more aggressive stance from behind.

Although it provides the Subaru with that signature boxer sound, it is not optimized for flow or power. This design is great for low-end spool, but the factory exhaust manifold runs out of steam higher in the rev range. To relieve this issue, other manufacturers would design a more equal-length header with larger diameter runners to make up for the performance. Because of these reasons, GrimmSpeed has created a header that would offer the best of both worlds meaning excellent power delivery throughout the entire RPM range, while still delivering that flagship boxer rumble.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eGrimmSpeed presents a proprietary design that utilizes an innovative setup where each bank of runners is equal length. One set is 1.5 times the length of the other which provides the ruble sound while maintaining the performance of an equal length setup. This manifold utilizes a single-piece, mandrel-bent runners to minimize disturbances to the exhaust gas along with an extremely durable cast 304 stainless steel collector to keep each bank of runners truly equal length which is very difficult to accomplish with a 4-into-1 welded collector. The low-angle merge of this collector allows for a faster spool and unbeatable off-boost throttle response. To match the flow, the collector features machined internal diameters to perfectly match the 1 3\/4\" primary runners and 2\" secondary pipe which eliminates unwanted \"steps\" in the exhaust flow.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eDuring the engineering process, GrimmSpeed scanned the underside of several EJ engines using a FARO arm which allowed them to design and simulate their header in a digital 3D space to find the optimal balance of runner lengths and angles for the best performance possible on an unequal length setup. They then 3D printed a number of different configurations to narrow the most optimal final design. They were able to form the header around a variety of different STI oil pan setups from factory to the most popular aftermarket options. Once they were satisfied with a design, GrimmSpeed put the manifold through months of punishing performance and longevity testing. When compared to the OEM exhaust manifold, GrimmSpeed had produced +25 HP and +25 FT\/LBS with a quicker spool even when compared to the best unequal and equal-length aftermarket offerings,\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eNote\u003c\/p\u003e\n\u003cp\u003eHeader wrap or having the headers ceramic coated will void the Warranty\u003c\/p\u003e","brand":"GrimmSpeed","offers":[{"title":"Default Title","offer_id":45763448504609,"sku":"grmGRM113026","price":1029.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/9029\/2257\/products\/addf196aaf37d3025c9db6799ee560a5.jpg?v=1697904808"},{"product_id":"33004-af002-hks-legamax-center-pipe","title":"HKS Legamax Center Pipe - 2008-2014 Subaru STI Hatchback","description":"The Legamax Center Pipe will improve the exhaust performance in the Subaru STI Hatchback. \r\n\u003ch3 align=\"center\"\u003eHKS Legamax Center Pipe\u003c\/h3\u003e\r\n\r\n\u003chr\u003e\r\n\u003ch4\u003eSPECS:\u003c\/h4\u003e\r\n\r\n\u003cul\u003e\r\n\t\u003cli\u003eSUS304 Stainless steel construction\u003c\/li\u003e\r\n\t\u003cli\u003e65mm inner pipe\u003c\/li\u003e\r\n\t\u003cli\u003eDesigned with smooth bends\u003c\/li\u003e\r\n\t\u003cli\u003eRelieves the exhaust of restriction and turbulence for better performance\u003c\/li\u003e\r\n\t\u003cli\u003eImproves the horsepower and the torque\u003c\/li\u003e\r\n\u003c\/ul\u003e\r\n\r\n\u003cp\u003e \u003c\/p\u003e\r\n\r\n\u003ch4 align=\"center\"\u003eIMPROVE THE EXHAUST FLOW FOR BETTER PERFORMANCE\u003c\/h4\u003e\r\n\r\n\u003cp\u003eThe HKS Legamax Center PIpe has been designed to improve the overall exhaust flow.
