My shit box only just makes it IF you come straight off the motorway straight to testing don't let it cool down you have no chance

It does have some rasp as I have the SS un-resonated centre section - which I like personally. If you fit the resonated centre it practically eliminates rasp (AlexGTT has such a setup).

By far the biggest culprit of exhaust drone is the fitting of aftermarket 100 cell cats as I have experienced this firsthand.

My car is generally 100dB at track days and passes straight away so long as it is hot as you say.
