4/5

It seems to have increased intake air a little more than OEM.

I used this product on my yz450f, which is a course-only bike, and I think it increased the intake air a little more than the OEM. The intake and exhaust sound is much more energetic than a commercial motorcycle because it is a racer.
The intake sound has been improved a little, and the low speed torque and the start up have become pleasant.
It looks Race ish and I don't think it's a bad buy.
