have you had a chance to decrease the starting rpm to lower the cold start volume?
sounds raw as hell, im just afraid its too loud at startup, my neighbors would want to kill me..

We did my car and 2 harleys last weekend, all 3 got header/exhaust. I'm sure my neighbors hate me right now. I started working from home in the mornings and don't head into the office til 9 or 10, so it hasn't been much of a problem so far.
I don't know how to lower the starting rpm. I assume there is probably an off the shelf tune similar to the one I already have that will correct it, but I haven't had the time or desire to find it just yet. I'll figure it out and give it a try, but I can tell you this, if you can get it to stay below 1,000 rpm's it is actually quiet as a mouse. It's incredible the difference 4 or 5 hundred rpm make. At 1400, it rattles things in my bedroom.
I'm having a hard time feeling out the gains because it sounds so aggressive now that everything feels faster. It's hard to differentiate between how it feels and how much faster it actually is. Also I've only been doing spirited driving. There are places I could redline it through the gears and get away with it. Every day I take a right at a stop sign onto a 50mph road, but with the exhaust noise and back end swiveling around it just causes such a scene...
If you are worried about the noise, it's really not unpleasant for normal driving. If you want to keep it quiet on the road it's not that difficult. It starts getting loud above 3500 i think. I'll get some driving video that shows the rpm this weekend.
