Most likely not a good idea to rev a engine not under load till it hits the rev limiter . Car sounds good a bit deeper than the stock exhaust to my ears.

not sure what joez uses for resonator and mufflers but usually the material inside those are the stuff that "breaks in"

and i doubt you will notice much of a difference

I wonder if 102 octane will help?

It won't

reducing weight and drag radials would make the most difference

theres also breaking in of the muffler deadening material. On my 3IS JoeZ it took several days for the sound to settle

I can confirm this with the Borla once I sold the hks ssm and installed the Borla the car would break loose with traction on and I had Michelin pss . Will update soon on the 1/4 mile runs so far my best was 12.622@113

Rsximus have you taken yours down the 1/4?

Just installed mine. It sounds awesome, buy I find it a bit loud. Hope it quietens down a bit after some more driving.

Fitment is good, no cel's, nice piece overall.

I don't think you can expect it to quite down....

However chances are you will begin to grow accustomed to it. While cruising at a set MPH, its really almost silent, its when you press the gas or down shift thats when you can hear it.

Yes, I find if you either drive slower (which is a good thing, I won't get anymore tickets ) or drive quicker once up to speed it is not so bad. But if I drive it like I usually do which is a bit heavy footed off from stationary, then it roars too damm loud at around 2K rpm's and it's like as if you have summoned the devil .

It's just that I been reading on some posts here and been told by the Lexus dealer I got the Joe Z from, that it will settle down a bit more after a couple weeks of driving so that's what I am hoping it will do.

On a side note I get funny reactions now, people's faces looked puzzled as to why does a Lexus grow like that?

In my experience with my previous 3 cars with after market exhausts, its both, you get used to it and the noise reduces.
