Agency Power Valvetronic Exhaust System Mercedes G500 | G550 4x4²


Agency Power

Model #AP-G65-170

The Mercedes Benz G500/G550 4x42 is one of the most unique vehicles on the road today. The 4.0L Bi-Turbo V8 gives it great power with tons of bite. The Agency Power Valvetronic Exhaust System for the Mercedes 4x4 adds an aggressive tone when you want it, quiet when you don’t. The dual oval tips with valved mufflers sit before the rear tires on each side of the squared.

The Agency Power valve controlled exhaust gives the user the ability to control the performance and sound of the exhaust with the push of a button. The high quality dual, TIG welded stainless steel system, is like fitting an OEM component to your 4x42. Including all necessary hardware for fitment, there is no cutting, welding, or adjustment required.

At the push of a remote button, a valve opens up on each muffler giving you a sport mode with maximum performance. Where other exhausts are always loud, the Agency Power exhaust can be loud only when you want it, giving you a roaring sound, or quiet for smooth city or freeway cruising. With the valves closed, having a conversation, talking on your phone, or listening to music is comfortable. The performance you get from sport mode exceeds others systems in sound and quality. If you’re looking for an exhaust that gives you the best of both worlds, then the Agency Power Valvetronic Exhaust System is the only choice to keep the luxury of the Mercedes G500/G550 4x42.
