Pretty sure thats been disproved by Nurrish, Myself & now Sam who have all gone above the "safe" 400 mark.
As said before, torque kills these motors - not HP
Did'nt Nurrish blow his up?!
No.

Guess I'm in here then
I was 22 when I fitted the Nur Spec, Ichiba y-pipe & ebay decats.
Then a few months later I cut the silencer out of the Nur Spec & y-pipe & replaced them with straight pipes - and swapped the decats for HFC
Then at 23 I switched to a GReddy single
Then after about a year I'd switched to a set of japspeed decats & removed the silencer from the Greddy and fitted DC headers.
Then I fitted a supercharger & switched to Tomei decats
There is. Any exhaust that is modified to be louder than standard for its age and type is a failure - its all down to the testers discretion. Quite a new one (last 2 years or so) due to the amount of Barry cans. Police can also pull you over and test db levels as they do with window tints etc
Testers discretion - If its down to them then surely there is no set legal limit as it would be either a fail or a pass
