I don't know Camerashy - stealing my thunder!
Welcome to the Fujitsubo club (well, when you get it and make it fit!).
As with all of these things, when one makes the assumption that a bolt-on part will bolt onto a Z without putting up a fight and giving more grey hair, one pays the price!
It took a tad longer than intended and assorted experiments to get a reasonable hanger arrangement to get it properly aligned, but it fitted good in the end. The manifold was an excellent fit on the engine - the thick, high quality flange matched the thickness of the intake manifold exactly - no need for imaginative shimming like was the case with the previous MSA manifold. The only thing we had to do was turn the crankcase vent pipe so that it angled forwards and down as it fouled the front primary otherwise.
I only took a couple of photos and no video yet. I've only driven it twice since fitting and haven't had a chance to really go for it yet. However, it sounds a lot different to my old system (a 2.5" MSA setup with no mid-box and a turbo back box). Quieter on idle, but a deeper, smoother tone. Sounds much more bearable inside the car! When you rev it up though, IMO it sounds excellent. Not as aggressive as my old setup, but definitely pleased with the result.
Also, it has definitely improved performance - in the past my car suffered a torque hole around 2250rpm - as demoed on the dyno graph from the setup at Ric Woods' a couple of years ago. According to my right foot dyno
)), this has been virtually eliminated as the car pulls smooth and strong from 2-3000rpm now. Unsurprising really - the pipe has a crossover mid-box which hangs behind the gearbox - I assume doing the same job that long y-pipes on other systems have been shown to do in lessening certain torque issues.
