It's not as different as the Gold amount you pay, and it's almost as effective as just stopping secondary Air.
If you are going to use it, I think just the one that connects to the Blowby hose would be fine, and a similar Valve that doesn't have backflow would work as well.

Product detail
**Blue color only..
Focusing on the customer's comments at the T-REV free trial event held every weekend, we have set the specification that you can feel the engine braking well while keeping the engine braking moderately.
Compared to stock T-REV, T-REVα system can reduce crankcase internal pressure more than 2.5 times for single and twin engine and more than 10 times for multi-cylinder engine.
This not only makes the engine braking milder, but also makes the acceleration smoother when the accelerator is opened.
These changes will greatly contribute to improving your riding and reducing fatigue when touring.
T-REV α system is composed of unique piping and is designed exclusively for each model.
