Thanks for all.
Sorry we are still working with our web site as we have too many details to put them on it.
For the valvetronic does some job not just close / open the flap, it really gets more torque and airflow at same time.
As we know, for race use we do keep the exhaust as straight as passable, but when we using it in street, it gets too loud and we lose torque as we never keep the engine in high rev all the time.
There are several companies making the exhaust with valvetronic (or same method of design), Kreissieg from Japan, Capristo from German also KKS performance from German.
We all using different technology to control the valve flap.
I believe they only offer to control by remote without any automatic system except Innotech and Capristo.
Our system including a Valve Controler ECU, which can be setup by user to control the valve automatic by Rev and Gas pedal.
You can setup your own rev or fuel pedal (e.g. 1/2, 2/3 or full fuel) to oepn the valve.
Of course, the valve can also be control by manually by our remote control.
Basically, the valve close gives more torque and when it open it become straight to gives more airflow to receive more power.
Ths system isn't cheap if compare with non-valve exhaust system but it does really give more power and sound control.
Please feel free to PM me if anyone interested with the price. Thanks
