This Invidia big piping header is a game - changer for your Subaru. It's designed for 2002 - 2014 WRX, 2004 - 2021 STI, and 2005 - 2009 Legacy GT models. If you've installed a big turbo and tuned your Subaru to the limit but still can't reach your desired peak performance, this header is the solution. It keeps all the great features of Invidia products and boosts performance further. The wider exhaust runners offer unrivaled exhaust flow, providing a smooth, turbulence - free exhaust stream to your turbo. This results in faster spool, better response, and most importantly, more power! Please note, it's not suitable for stock cars or small turbo upgrades. 2.5L turbo Subies are well - matched, while 2.0L models need to convert to the 2.5L oil pan. Some 02 - 05 WRX may require a 2.5L STI oil pan, and 06 - 07 WRX need an STI oil cooler and oil pan. Also, it's not legal for sale or use in California on emission - controlled vehicles.
Using this Invidia big piping header is simple. First, make sure your Subaru model (2002 - 2014 WRX, 2004 - 2021 STI, or 2005 - 2009 Legacy GT) meets the fitment requirements. Check the oil pan and cooler as needed for your specific model. Install the header according to the standard automotive installation procedures. When it comes to maintenance, regularly inspect the header for any signs of damage or leaks. Keep it clean from dirt and debris. Remember, this product is not for stock cars or small turbo upgrades, and it's not legal for use in California on emission - controlled vehicles. If you have any questions, don't hesitate to consult a professional mechanic.
