Agency Power’s new line of Electronic Valve Controlled Exhausts set the standard for today’s savvy buyer. With the push of a button, the user can select “aggressive” or “sport” mode with unique sound properties. No more compromises!

Agency Power set out to produce the best exhaust system to appeal to the entire market. The solution is simple, create a high performance, quality built product with variable exhaust sound and performance. That is where this electronic valve controlled system thrives. The Agency Power muffler gives the user the ability to control the performance and sound of the exhaust with the push of a button or throttle position.

Valves mounted near the muffler allow exhaust gases to either pass straight through for performance and a louder sound or be diverted into the muffler for a quieter sound. Constructed with 304 stainless steel and tig welded ensure a quality fit and durability that is an Agency Power standard.

The Agency Power electronic valve controlled exhaust is a must for both the street and the track. In addition to the Valvetronic line of exhaust, Agency Power continues to manufacture exhaust systems for hundreds of popular models.

On what kind of a dyno does an M5 only make 348hp, and what's that big dip in the stock graph towards higher RPMs? That big performance gain above 5500rpms from an exhaust system doesn't seem like a typical type gain from an exhaust.

It's a Mustang Dyno. They typically show lower, more accurate ratings. I grabbed this from their website:

"Mustang Dynamometer

Offering our clients a world of testing solutions and technical expertise.

Mustang is the dynamometer of choice for serious performance tuners and aftermarket product developers for a reason - they know the facts. Fact is - in order to get the best tuning results, you need a dyno that applies an accurate load, like the car would see on the road or track. Other dynos don't compare and will give higher horsepower readings to try to impress. But if the power you thought you found on your dyno wasn't based on actual real-world loading, chances are it won't be there when you need it at the track. The best tuners and power product developers in the world know the facts - Mustang Dynamometer is the most accurate and reliable dyno because it provides real-world loading and precise control."
