Who would you contact if needed a BIG ASS can to use on restricted track days?
Maybe 6-700mm and thick motherf...to get down around 92dB
Zorstec??

...and no, a J-lo fart from that large trunk won´t get down to 92dB....

Volvo trucks????

It´s always a funny one in the bunch....GFY

The std Akrapovic can that came with my system is around there.. I can fart louder than it ...

If you are talking track day use then I'm assuming they will noise test according to race regs - which in the UK (for twins) is at 5000rpm at a set distance. In which case 92db is whisper quiet. Can you maybe modify a standard can to fit?

92 dB whisper you say?
On Assen the restriction is 88 dB.

I've only known the noise test to be taken at an rpm dependant on the engine's stroke.

That could be a way out!

In Sweden they have a mic at the straight measuring drive by...of cource one could go by in idle but....how fun is that!?
But idea of altering a standard is good!

Although the standard can weighs about 1200kg.
You could fill it with Helium!
