I keep reading posts about it being too loud. Honestly, it was for about 2-3 weeks. It was borderline annoying. But after that, it really quiets down, and am really happy with it.

Does anyone NOT like it after the break-in? Any regrets? Just wondering.

 

My exhaust is actually quieter since I installed the headers. And what little drone there was at 3K is now completely gone with the headers as well. I absolutely love the sound of the exhaust and headers combo. Would make a sound clip but don't have anything to record with.

 

mine is perfect. it was loud the first few days...but now it kicks ****.

 

What's the butt dyno like? I know the actual numbers, but does it feel like you're gaining that much?

 

You feel it more in the upper rpms. It's nothing phenominal, but you know it's working.

 

I agree with this statement.

I love the exhaust. Also, the Z still feels quicker than stk and pulls very nice up top.

 

I cant even hear my damn exhuast. I can in lower RPM and then when i get High in RPM all i hear is the cold air intake. That is one loud *****

 

That's so wierd, I found my Borla exhuast got louder after break-in, not more quiet.

 

I like my Injen exhaust... on someone else's Z. It sounded great driving away.

I am much happier now, plus the torque drop was ridiculous, when I put the stock system back on for a while it was like I suddenly got a burst of power.

My hearing isn't so good.
