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 unique 3-bolt flange design between the manifold and uppipe, ensuring a stable, air-tight connection. With a huge 45mm inner pipe diameter, your exhaust will exit super fast. The welds are amazing—you've got to see it in person! Notes: 02 - 05 WRX needs a 2.5L STI oil pan. 06 - 07 WRX requires an STI oil cooler and STI oil pan.
Using this product is straightforward. First, make sure to check if your Subaru WRX or STI model year requires any specific oil pan or oil cooler as noted. Then, carefully install the headers and the included uppipe, taking advantage of the stable 3 - bolt flange design. When it comes to maintenance, since it's made of stainless steel, it's fairly durable. But it's a good idea to clean it regularly to keep it looking great and functioning well. If you notice any air leaks or issues with the welds, have it checked by a professional.
