A means for improving performance was taken advantage of during the design process as well.
Of course, our own spin of improvements, besides the obvious had to be made to assure set it and forget reliability that comes with our products. We pushed on the screen of new OEM pickups and several popped wire strands, without a lot of effort.īeing known for making the best Subaru Performance Oiling Products money can buy, addressing this was right up our alley. The other is that the spot weld process embrittles the screen. One is that the screen is creased where the retaining ring is crimped over it. There are a couple of flaws with this process. The OEM pickup screen is crimped in a retainer and that assembly is spot welded into the pickup ‘can’. At the time of failure, I had assumed this was just the kind of luck I had, but after hearing that other shops had similar experiences, we dug deeper. The OEM part had not prevented metal bits and chunks from entering the engine. Why had the oil pump filled with debris? The OEM pickup screen had failed. I’m sure you can imagine the consequences of instant oil pressure loss. As you can see, debris went into th engine and made its way into the oil pump. The engine had blown, but the violence was significantly more than just the bent rod we had hoped for. I came across this many months ago, during turbo kit testing on our shop 2015 WRX.
321 is made with the alloying element Titanium.Like many of our other products, this is a solution to a problem. Approximately an 8-10 week leadtime.ģ21 Stainless Steel offers benefits over common 304 Stainless Steel.

Large Radius Free Flowing Mandrel Formed Bends Maximize Flow potential. This means a 321 header will deliver more thermal energy to the turbocharger, improving Responsiveness and Efficiency. 321 Stainless Steel conducts less heat that 304 Stainless Steel. 321 was developed by the aircraft industry specifically to address longevity issues with pressurized turbocharged manifolds addressing cracking from lower quality grades of stainless steel like 304. 321 offers Increased Strength and Toughness at elevated temperatures, making it less likely to fatigue and crack. This increases the material cost significantly, but for a turbocharged application, offers advantages over 304. 321 is made with the alloying element Titanium. Available for the traditional OEM (or OEM style) turbocharger, or Dual External Wastegate version to deliver Maximum Performance Potential.ģ21 Stainless Steel offers benefits over common 304 Stainless Steel. Equal Length Twin Scroll Design improves exhaust gas scavenging, increasing the engine’s ability to make power. Twin Scroll Stainless Steel Header for 2015+ Subaru WRX FA20 by Killer BĪdd MORE POWER to your FA20 Turbocharged Subaru! The factory OEM manifold is designed as a cost-effective component whereas, the Killer B Motorsport Performance Header is designed with the goal of Maximizing Exhaust Gas Performance and Increasing Power.
