Headers and Loudness
I have a 2004 ZO6 with no engine mods other than a CAI. I am wanting to get headers installed but am concerned about how much louder it will be. Anybody have any comments on this? Anybody near Atlanta that could let me hear their car? I don't mind louder, I just don't want to not hear my radio, conversation, etc. Eventually, I would like to get a S/C and figured that this was the first step...
Feedback very much appreciated!

my opinion... different designs will have different sound qualities. i've read that LGs are louder than Kooks in general. For some thats a plus or minus depending on what you want.
also, whatever LT you go with, if your goal is to keep noise increase to minimum... keep the stock Ti pipes. Aftermarkets sound different with various headers but I believe all sound much louder than the Ti pipes.
In my experience, the Kooks 1 3/4 with factory Ti pipes sound marginally louder than factory under normal conditions which i love. At WOT it sounds like a beast.
Good luck.

I chose Kooks, and I can tell you from personal experience that my car has the same or actually less exhaust noise on cruising. I attribute this to the deeper tone. On cruising, it is barely audible.Now if you put your foot into it, that is an entirely different story.

I installed a complete StainlessWorks system (SS headers to SS tips)on my 02 ZO6. I am very sensitive to TOO much noise and did not want a system that would rurin the interior quite!
Well, the Stainless Works 3" mid section with X pipe and the Stainless works mufflers sound wicked!!!
They even impressed the wife and she WILL NOT drive in a loud car!!! 
The system is not as loud as it is throaty and deep! It screams at WOT!
I am very happy with the sound and even more pleased with the new found HP/TQ!!!!

Deeper sound is fine. More "Growl" at WOT is not a problem and will probably be enjoyed. I also plan on keeping my stock Ti exhaust.
I just don't want my exhaust note produced by the headers overpowering everything else going on with the car!!!

I guess I will find out how loud my vert will sound after I install TPIS Longtube headers with X-pipe, and no cats coupled up to the SLP Loudmouths!!

I have Corsa Indy Pro mufflers on before the LGM LTs and they sounded find. After the LTs, the sound was loud enough to effect the tides and attract way too much attention for my liking. I think they were around 98dbs at cold start and 120 at WOT.
Dumped the Corsas and installed stock Ti mufflers and the world once again let's me drive on without too much notice.
