From Agency Power:
One of the best ways to increase performance is with high-flow headers. The Stock M5 and M6 headers are small diameter and restrictive which robs your car of horsepower. Agency Power has released a performance header that utilizes high flow cats and larger diameter pipes. This combination allows the exhaust to travel into the rest of the system much faster and carry more heat away from the engine.

Constructed of 304 stainless steel and mandrel bends, the Agency Power header is among the best performing on the market. When coupled with supporting mods, the Agency Power High Flow Cat headers are capable of producing upwards of 50whp. Another great advantage to the Agency Power high flow cat headers is the weight reduction they offer, a difference of 10lbs.
