I love my YZ450F

Didn't realize that. I'll see how it runs with the quite core in, but more than likely ill end up ordering this. Thanks

No problem.

It's possible you're getting the above insert. If so, thank you for riding quietly. I run the Q4 in full stealth mode and from my seat the intake noise is louder than the exhaust. As for power loss, meh, still has plenty for me. And my friend's on their CRF450Rs that ate my roost on our one and only drag race think it has plenty of power too.

Yes that is what comes with my exhaust. That's the 94db insert correct?
