Recently, we had a customer ask how we routed our Agency Power Mercedes C63 AMG Valvetronic Exhaust’s Vacuum line.  We thought we would put up a blog post showing the routing method our techs used for your reference.

These photos show where we installed the controller box, mounted the canister, ran the vacuum lines, and tied into the car through the engine bay.

The tech followed one of the hard lines from the rear of the car into the engine bay. A little creativity might be required.

The tie in point is into an EVAP line (engine… Read More

Another BMW M5 is in the shop getting some Agency Power Headers installed!  Check out the pics below!

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… Read More

Our Porsche Panamera Turbo Y-Pipe in both aluminum and carbon fiber is a great add-on with a proven 30HP gain!  Recently, the crew over at Kleemann USA installed this carbon fiber piece in a customers Panamera.  Besides supplying incredible Mercedes products, the Colorado based company also does installs for other vehicles too!
