Part #: 17217. Crafted from T - 304 stainless steel, this Borla Unequal Length Header offers top - notch performance and durability for your WRX or STI. It boosts low - end torque and throttle response across the RPM range. Backed by a million - mile warranty, it's the only header you'll need. This header can be directly bolted to a stock or aftermarket uppipe. We suggest replacing the gaskets for a leak - free install. Note: 02 - 05 WRX may need a 2.5L STI oil pan, and 06 - 07 WRX requires an STI oil cooler and oil pan.

Using this Borla header is easy. First, make sure to check if your vehicle model requires any special parts like the oil pan or oil cooler as noted. Then, bolt the header directly to your stock or aftermarket uppipe. Don't forget to change the gaskets to avoid leaks. For maintenance, since it's made of T - 304 stainless steel, it's quite durable. But you should regularly check for any signs of wear or loose bolts. Keep it clean and it will keep performing well for a long time thanks to the million - mile warranty.
