What is your track day noise reading?
Just a quick survey of exhaust type and noise level recorded at a track day or similar? I am going to Castle Combe in a couple of weeks and I hear they are quite fussy about it. Don't want to go all the way there for nowt!
So....what was the db of your car???

type 20 full miltek with sports CAT on a twinscroll Turbo 97dB @ 4500 rpm static, measured at Castle Coombe.
at Donington i was doing track session on a 98db day (time Attack day) I was short shifting on first session by the 2 bridges and no problems but got over enthusiastic on second session and recorded 104 db by driveby meeters Black flagged

This is an issue which is only going to get worse, I was talking to a couple of TDOs last year and both were saying there is a very high possibility that we might see a nation wide limit imposed, one mentioned 103dB (not too bad) and another mentioned 98dB.. which could cause problems.

Car was up on ramp today and I have had a look to see what it is. Looks like a standard downpipe with cat and then an Apexi aftermarket exhaust (already on the car when I got it). Car is a type R ver3.
I have arranged to borrow a noise meter so fingers crossed!

Mine was 96db and then 97db @ static 4500 rpm both tested at castle combe last year thats with a magnex turbo back system (no cats) and is 2 1/2 inch diameter with the 6x4 oval tailpipe. Only running 270 bhp with a few mods. You could put one of those nasty silencers on that you can hire from castle combe to get the noise down if you need to (not sure how you'd attach it though).
