Part #: PSR - HEA - WRXGDA - U. Our headers are a masterpiece! Crafted entirely from T304 stainless steel, even the flanges. This set comes with the pictured uppipe featuring our exclusive 3 - bolt flange design between the manifold and uppipe. It ensures a stable, air - leak - free connection. With an amazing 45mm inner pipe diameter, exhaust exits super fast. The welds are truly amazing! You have to see it in person. Notes: For 2002 - 2005 WRX, a 2.5L STI oil pan is required. For 2006 - 2007 WRX, an STI oil cooler and STI oil pan are needed.
Using this product is straightforward. Just install the headers and the included uppipe in your Subaru WRX or STI according to the vehicle's manual. Make sure to check the oil pan and oil cooler requirements based on your car's model year. For maintenance, regularly inspect the headers for any signs of damage or corrosion. Since they're made of stainless steel, they're quite durable, but a gentle cleaning every now and then can keep them looking great. If you notice any air leaks or abnormal noises, it might be time to check the 3 - bolt flange connection. Also, keep in mind the specific oil pan and cooler requirements for different model years to ensure proper performance.
