So, a few updates.
Few weeks ago I had a package arrive on my doorstep, granted it was a few months late due to UPS losing it... but we got there in the end
A K-Tec Recessed Supersport. It's lovely. Car definitely has more mid-range and sounds awesome to boot. Droney as f**k when on light throttle (worse with the windows open too), but is almost dead silent when cruising, even at 100/110kmph.

By coincidence, right after installing the exhaust my engine developed a ticking noise. Turned out that it was a loose spark plug. Am rather glad I figured that out before anything bad happened.
Other things: replaced my ELF gearbox oil (only 8,000km old too) with Redline Lightweight Shockproof stuff... what a difference. Shift is amazingly smooth now.
Also had the car dynoed about a month back with the old leaky exhaust, pulled 107.3 fwkw, which is about 144hp @ the wheels and using 20% loss, pretty much bang on 173hp
