Agency Power High Flow Cat Headers BMW E60 M5 E63 M6 05+
One of the best ways to increase performance is with high flow cat 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.


No check engine light will occur and no ECU modifications are needed.


Gaskets are not included and are available for an additional fee of $120.00

Agency Power Exhaust System E92 BMW M3 08+
The ultimate driving machine now sounds like a true sports car. Agency Power has taken the E92 BMW M3 big V8 engine and given it some sound steroids. The Agency Power exhaust has a great tone which gives your car that race sound many desire. The Agency Power exhaust system has been engineered and dyno tested to not only improve the sound, but gain horsepower, and improve top end performance. After months of testing, Agency Power has completed this beautiful dual muffler design system.


The all T304 stainless steel exhaust is TIG welded and polished to a mirror finish. The exhaust uses the existing hangers for a secure rattle and clearance free fit. To stand out amongst the rest, the system features quad 3 inch tips in either rolled stainless or in titanium with a burnt finish for an exotic look. This muffler section also includes the S pipes to give you a complete bolt on exhaust system. As tested on our Mustang dyno, the exhaust gain power throughout the RPM band and its peak gain was 5hp and 3ft/lbs of torque, however with a software upgrade this exhaust can reach 30hp and 20ft/lbs of torque (as shown on dyno graph). A great addition to an already well factory tuned car.


The exhaust is designed to fit the E92 M3 coupe only.
