Latest update, got the mot'd sat and it promptly broke down half a mile later. Luckily it was just the main battery feed wire falling out of its crimp, not sure how yet as its been like that for 2 years no problems.
And then on the way home via a tyre center to get my leaks sorted a dopey blond in a 106 nearly rear ended it, luckily only one side of her brakes worked (standard on a 106) and she skidded beside me rather than into!!
I have my new exhaust tested now and it's a little on the loud side, for starters it's still the eBay manifold but now with 2.5 collector and no space for the cat anymore, not even a decat I've just gone straight through.
The exhaust is a hks from a evo 4 so it's 2.5' before the silencer then 3' and a 4' 3/4 tail pipe, I wanted to remove it but haven't had time yet.

It's loud, 99db according to the iphone. And sounds like a proper ricer machine, hope to get a bung to quieten it down a little.
New wheels are looking good, the supra 16x8 with r888s feel much more planted and stable, I don't mind the odd wheel look and I have the supra 9' rear to test out once I fit the 5 stud hubs.
Next steps are a full engine service, and rear brake conversion
It was also nice to finally get out and try dino's gearbox. Very rapid through the gears, takes alot more effort to keep up with it but looking forward to the lsd on track rather than the stock m2a4!!
