can I have the cake and eat it too?

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!).
