As one of the finest automobiles delivered from BMW, the E46 M3 has lived up to all its expectations as a true performance car. As enthusiasts try to squeeze any additional horsepower out of the inline 6 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 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.
Headers are sold as a complete set to fit the 01-05 BMW M3 E46 vehicles. Headers fit both the SMG and 6speed manual transmission cars. Professional installation is recommended.
