Part #: PSR-HEA-WRXGDA-U. Our headers are a true 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, ensuring a stable, air-tight connection. With an amazing 45mm inner pipe diameter, exhaust gases exit quickly. The welds are incredibly well - made, and you have to see it in person to fully appreciate it. Notes: On some models, 2002 - 2005 WRX requires a 2.5L STI oil pan, and 2006 - 2007 WRX needs an STI oil cooler and STI oil pan.
Using these headers is straightforward. Just follow the standard installation process for exhaust components on your Subaru WRX or STI. Make sure all connections are tightened properly to avoid air leaks. As for maintenance, regularly check the welds and connections to ensure they're in good condition. If you notice any signs of rust or damage, clean the affected area with a stainless - steel cleaner. For long - term performance, it's a good idea to have the headers inspected by a professional every once in a while. Also, keep in mind that some WRX models may require specific oil pans or oil coolers as noted, so make sure you have the right parts before installation.
