Our Valvetronic exhaust delivers both power and dynamic valve control to the driver's seat. The full system comes with a remote control module including 3 different modes: on, off, and auto. In on mode, the valves are fully open for maximum flow and power, releasing a breathtaking racing sound with an incomparable clean tone especially when accelerating. In off mode, the valves are closed and volume is reduced for a comfortable cruise. The auto mode enables the system to detect the engine rpm and fuel pedal signal to automatically adjust the valve movements for a dynamic driving experience.

Wow ! That sounds insane! Good Job! If you can provide a dyno chart that will be even more convinsing!

 

We've dynoed a few. Good sound but that's about it, power gains are not consistent

 

Hello! May I ask? What do you mean by inconsistent of power gain? Is it not gaining power at all or just very little gain? Please advise tks!

 

Lower than expected and loses in a few cases. Closed valves in C63 AMG were a major loss

 

 

Valve opered or closed?

Do you have dynos of stock software/ stock exhaust vs stock software/ IPE exhaust?

 

Sir, may I have your email? We are glad to deal with the problem in any case, please feel free to contact us via mail below.

I'm trying to obtain comparable info, that should be for the common knowledge of this forum, not prívate info. Why would you say there's a problem?

 

So... Sir do you mean their GT3RS exhaust will also lose power when its valve close? Tks!

 

I'm saying... be aware it could.

 

The sounds insane also

 

The sound will be amazing, that's a fact

 

Tks for your notice!
