Using this Prosport header and up - pipe set is straightforward. First, make sure your vehicle is a 2002 - 2014 Subaru WRX or STI. If you have a 02 - 05 WRX, you might need to install a 2.5l STI oil pan, and for 06 - 07 WRX, an STI oil cooler and oil pan are required. When installing, pay attention to the 3 - bolt flange design between the manifold and up - pipe to ensure a proper, air - tight connection. During normal use, you'll notice the improved performance as the large 45mm inner pipe diameter helps exhaust exit fast. For maintenance, regularly check the welds and flanges for any signs of wear or leaks. Since it's made of T304 stainless steel, it's fairly durable, but keeping it clean will help it last even longer. If you see any issues, it's best to have a professional mechanic take a look.
