Agency Power headers are an affordable way to bolt on more HP

Due to the fact that modifying cheap $200-500 headers is either costly, or very very time consuming for the DIY, we simply don't carry products that are inconsistent. Rather, we prefer to offer these affordable, yet well fitting headers from Agency Power, who stand behind their products and have tested to insure a good power gain over stock.

These headers offer:

Fitment that is better than knock off brands

Good power gains, especially with an ECU flash

Elimination of cats for best power gains

High polished Stainless Steel finish

3-month warranty from Agency power

From Agency Power:
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 catalysts 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. All Agency Power products come with a 90 Day limited warranty.

Feedback about S54 headers...
We often get asked about our experience with "Ebay headers" and it's always been a roll of the dice.
When coming from sources that are not controlled, that simply blow out mass produced items to the lowest bidder, you don't know if your headers are going to be getting headers as "shown in the picture" or not.
Many S54 headers we have seen have awful O2 sensor fitment, or are impossible to install, and some don't even clear the floor of your car. About 1 in 8 properly fit when tested.
If we could sell you headers that worked perfectly for $300, we would be happy too... but until we find them, we recommend our confirmed choices above in each price range.
