Agency Power WRX/ STI Stainless Steel Unequal Length Header w/ Uppipe AP-GDA-175
As enthusiasts try to squeeze any additional horsepower out of their power plant, Agency Power has made it much easier with the release of their performance racing headers. The 321 stainless steel headers are a direct bolt on in replacement of your factory headers. The headers replace the factory catpipes and are to be used for racing applications.
The Agency Power Headers have thick flanges and amazing welds to insure longevity and strength compared to the competition. Each pair of headers includes the necessary oxygen sensor bungs. In addition to improving upon horsepower, the headers will also help achieve low end torque for the “off the line” power feeling.
