VQHR at high rpm-harsh?
Is this a bad thing? You drive a sports car, enjoy it! 
I rev my '04 VQ35DE to 6500ish in multiple gears on a somewhat regular basis and that's my favorite sound/feeling, and my engine is stock with the exception of a K&N drop-in.

I agree. The loud noise causes me to shift early, making me think I'm at a higher RPM than I'm at!

That's what I'm getting at- it sounds like like you're flogging it when you're really not. And the vibration is more distracting than the noise. I just wondered if anyone else felt this way. It seems like it "wants" you to shift at 3700rpm.

I know what you mean, but I think it's very different. I had a 2007 Si (same engine as RSX) and when it opened up, it got much louder, yes. It's really cool. The intake sound is actually tuned in that car with extra tubing to give exaclty the sound they wanted.
I only got rid of it because Honda wouldn't fix the tranny. That's why I have a 2008 VW GTI instead.
But it was much smoother. In the Z, you feel so much vibration through the steering wheel and everything.

Well I have the 03 DE. I also have a 06 RevUp and drove the 07 HR when considering trading. The 06 feels smother ( less vibratiom ) to me than both the others, but runs out of stem before the HR obviously. they are all loud up top and if you get aftermarket exhaust even moreso. The 03 of mine feels negatively harsh up top.
Just my .02

I love to take 2nd gear to 7500rpm,the noise with my Bassanti exhaust is almost intoxicating at high revs I have to be careful not to hit the rev limit.On the dyno in 5th gear it pulled hard and smooth all the way to the speed limiter.There was absolutely no indication that the revs were nearing the redline.
Hello, guys.
I have an '07 350z. Is there anyone else on here with an '07 or '08?
Both stock and with the Nismo CAI, I find that above 5000rpm or so, the engine gets harsh, very loud and almost like it doesn't like to be revved so high. I thought the point of the HR was to make it smoother. There's nothing WRONG with it and there's a lots of power, but is it just me, or does it seem like there's just no reason to rev above 4000rpm in this car?
The day or two after I had the Nismo CAI installed, it felt very different-less power down low and more smoothness up top. I figured the MAF sensor was learning. I don't know if the ECM was reset or not.
I disconnected the battery overnight to see if I could duplicate that behavior, but I can't.
Has anyone found this?
Anyone who wants to chime in with the 2003-2006, please do as well!
