Thanks for all your input...
John...What you describe is drone for sure. Some people are more sensitive to it, some have it but don't know they do until their wife tells them she's getting a headache..

I had a bit of that with my Vette after adding headers and HFC;s. One thing that helped a lot was a complete sound deadening of the rear hatch area. I used Damplifier from Second skin. It was a bit of work, but dampened the resonances and other noises nicely. I plan to do this to the Z as there is a fair amount of thin, undamped sheet metal back there. For $100 it may solve your problem and give you some other benefits too without pulling off parts.

The back of the vette wa like a big plastic bass drum!

John, I forgot to tell you earlier -- adding the Stillen headers will smooth out the sound considerably. That's one thing I immediately noticed after I installed the headers; the coarseness of the sound was gone. Now, for me personally, I was kinda disappointed because I loved the coarse/aggressive sound. But for you, it may be just the thing. The reason the Stillen headers do this is because they are equal length pipes. The stock manifold is not -- close, but not quite. The unequal length pipes is what gives off that coarse, aggressive sound. I have an interior sound video clip of my full setup (G3, headers, HFC, CBE). Have you seen it yet?

I believe you did tell me that. That is great advice. I am looking to kill that drone under med-hard acceleration found between the 3K-5K RPM range. Do you think removing the Berk HFC will accomplish this? And leave the Stillen CBE? Or the other way around?

Huh? My advice in my previous post was to consider keeping both and adding the Stillen headers, as the headers smooth out all the rough edges (plus give you a modest gain as an added bonus!).

John,

This is what my car sounds like, after adding the headers. It's not quieter per se, but the tone is smoother, if that makes any sense. You know what your car sounds like. Now compare with how my car sounds.

Hmm, given that, that set up might be too loud for me

That's funny. I wish my car was louder. Both my previous cars were louder so that's what I'm used to!

I need to disclose again...I am sorry I am being a wussy about this. And thank you all for all your advice and help! I am a little leary about adding headers. I hear ya on smoothing out the sound but it is not the rasp that is bothersom. I also am on the fence if my car is droning too much or is it tollerable. We all here like to fix "problems" we find in our cars and many times I find the drone to be a problem and other times I love the "power" sound and added performance (usually pulling away from a sti) LOL. I apologize for my ambiguity...and appreciate all your advice...
john

I think I am suffering from acute male vaginatis. I do love the sound and sometimes forget why I got this car and what it is good for. I appreciate all your help and advice. I think I will add sound deadining to the trunk area. I think that might take the edge off. Any advice as the best sound deadening stuff at the best price?

...You let people talk in your car?


J/K

Adding sound deadening will negate the reason for putting the exhaust on in the first place... You'll add enough weight to make up for the HP you gained. However, I still see that as the best solution because nothing will change in the end except that your car will still sound better from outside.

It consistently gets good reviews for effectiveness and cost..

How long have you had it. I've had a couple aftermarket exhausts, and honestly, you get accustomed to it after a while
