The Skunk 2 didn't ever bother me when I had it, but knowing what I know now, I'd never buy the S2 again. I'm glad you liked the vid. Some of the OG's from this site that are now on 9th civic are planning a mini meet at the Dragon in March if you'd care to tag along. :thumb:
I had a Skunk 2 60mm exhaust on my FG2, and it was fine, but my FA5 has a 3" Full Race exhaust and it has a much better sound than the S2. It's got a nice deep growl, but none of the annoying drone during normal driving like the S2 has. Like you I'd love to add a K24 block to my K20 head.
Sounds like you're well on your way. I haven't seen a TIC exhaust in a while, but always thought they sounded great from some of our early meets when I still had my first 8th gen. are you going to do any power adders in the future?
