You should not have any problems. The valve is there to vary back pressure. As your car requires more power, the valve will open accordingly to maintain the ideal amount of backpressure. By leaving the valve open all the time, you might lose just a little bit of low-end power, but in no way would this cause any problems to your car.

The flap doesn't affect backpressure, only sound level...

Yeah, what all did you do? Where is the valve located, and was it easy?

there's a little rubber tube that comes in to control the valve, it's detachable by hand.

And yeah, it's a sound thing, not a power thing.
