This Invidia header is a game - changer for your Subaru. It fits 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 the peak performance you want, this is the solution. The large - diameter header has all the great features of Invidia products. It's specially designed for big - turbo applications, with wider exhaust runners. These wider runners provide unrivaled exhaust flow, giving your turbo a smooth, turbulence - free exhaust stream. This leads to faster spool, better response, and most importantly, more power! Note that this product isn't for stock cars or small turbo upgrades. 2.5L turbo Subies (06 - 14 WRX/ 04 - 21 STi & 05 - 09 Legacy GT) are compatible. 2.0L models need to convert to the 2.5L oil pan. Also, 02 - 05 wrx may require a 2.5l sti oil pan, and 06 - 07 wrx needs an sti oil cooler and sti oil pan. And it's not legal for sale or use in California on emission - controlled vehicles.
Using this Invidia header is straightforward. First, make sure your Subaru model is one of the compatible ones (2002 - 2014 WRX, 2004 - 2021 STI, or 2005 - 2009 Legacy GT). If you have a 2.0L model, convert to the 2.5L oil pan before installation. For 02 - 05 wrx, you might need a 2.5l sti oil pan, and 06 - 07 wrx requires an sti oil cooler and sti oil pan. This product is only for big - turbo setups, so don't use it on stock cars or small turbo upgrades. Also, remember it's not legal for use in California on emission - controlled vehicles. As for maintenance, regularly check the header for any signs of damage or leaks. Keep it clean to ensure optimal performance. That way, you can enjoy the faster spool, better response, and extra power it provides.
