Some observations after 9 months off driving it.
The brakes are ferocious. I'd forgotten how you can just stand on them and it just stops. doesn't really matter how fast you are going in the first place.
The new exhaust is almost perfect. its a bit louder than i would like on WOT, but its no louder than the 2.2Milltek on cruise. This means I can creep back through town after a drive without waking the world and its friend up. It also means than i can hear radio 4 at 70mph

. The tullet mani makes it sound less busy. its quieter in the engine bay than it used to be, injectors and other mechanical noised can be heard more than before.
The whine is as present as it always was at higher revs and load, but does seem a bit more muted in the mid range load.
It seems to have gained in torque quite a bit. 4th gear from tick over to red line really is quite eye opening.
There was a comedy moment yesterday evening. I've not had a valid tax disc displayed for a long time (despite being properly taxed) so before going out yesterday i went to find the envelope and duly displayed the tax disc in the windscreen. it flew away somewhere along the a4

. I did a quick u-turn and actually found it in the hedge!
