I ordered an AC Noise Condenser off a recommendation from a user at the SN95 site. It attaches to the coil. They are prone to fail, and mine looked original and I'm not sure if it is even connected. Went to the muffler shop last night and got the Borlas installed (ProXS). They definitely tamed down the exhaust some. It still sounds good, but not as obnoxious. I'm not sure on the drone yet, I took the backroads home as it was a straighter shot. It's a pretty mellow tone, and I think it's going to sound pretty good at WOT. I didn't have a good chance to really get into it. Turns out the factory cats are gutted, so we just left them in place. There wasn't any heat in them and you could see where they had been cut/welded. That would also explain the raw exhaust smell. I also had him weld up the bung where the smog pump went in, I previously just had a hose with a spark plug clamped on it. I tried to look for the block to chassis ground while it was on the rack, but had no luck. I also saw the name plate/plaque on the header, but I couldn't make the brand out.
