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?
