Just to add a few more weights to Josh's list. The Hytech header weighs 12.4 lbs on my bathroom scale and the Hytech cat is 4.4. Not exact I'm sure but close enough. Now if I could only get the two halves to fit together.....

I've been running a new light weight (3.5 lbs) battery for almost three weeks in my daily driver...
Ballistic EVO2 16 cell 3.5 pound lithium ferrous battery. This saves about 24 lbs over the Interstate OEM sized battery that was in the car. Cost $240 plus $15 for brass posts with 6M bolts. It was mounted using the stock battery mount system with shorter tie down rods. The brass terminal posts had to be shaped (squared off) to fit within the plastic guard around the terminals.
Stats from Ballistic
I daily drive with this and left the car at the airport for a week. No issues with cranking and starting. The only notable observation was some hesitation when it was cold out, the temperature was down around 32F, but still no issue starting.
Charging this battery does not require anything special. There is a five pin special connector to be used with a $80 special battery charger which conditions the cells with the claim of increasing the life span. Here's a link to more information regarding the charger.
Anyone else using one of these?

Just installed a Greddy Racing Sport single exhaust on the car. It's the successor to the Ti-C. My scale only weighs in 0.5 lb increments so this weight will be approximate but it came out to 22 lbs (11 lbs for cat to axle flange section, and 11 lbs for axle back section). I haven't taken the silencer out yet - there's no way that's more than a pound but it could change it slightly.

Is this what you got?
According to Greddy it's basically the same thing as the Ti-C (they said the major difference was that the tip is stainless as opposed to burnt titanium). It's a 70mm single. Here's a picture I took.
BTW the weight tracks fairly well with the OEM cut-off and the cut-off back single using the OEM resonator as a muffler.

I think the picture you linked is maybe not actually for a s2000. I found this picture which looks the same as the racing sport, just with a different tip. - enjuku racing
I'm leaving the car on jack stands for a couple days so I can finish up all the other work for the season, so I haven't driven it yet. I'll report back maybe in another week.
I did start it up for a bit on the stands to check for leaks. It sounded great, very deep sound, significantly louder than stock of course but not ear bleedingly so and it seemed to have very little drone, at least with the silencer in.
Based on talking to people with the Ti-C (which according to greddy should be basically identical in sound and performance), sound should be about 91-92 dB or thereabouts with a header and HFC. So most likely good for qualcomm, and worst case if you get a warning stick the silencer in and it should be good.
That's part of why I went with this exhaust, so I don't have to worry about passing sound for a while and also so I can get more time to design my own, I figure it'll keep a pretty good resale value after a season if I want to do that. I'm also planning on trying to stick a turndown on instead of the axle back portion at some point, I'm thinking it might be OK for the least strict sound requirement venues.
