Re: One off exhaust can....
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?Killerwhale wrote:Who would you contact if needed a BIG ASS can to use on restricted track days?

I've only known the noise test to be taken at an rpm dependant on the engine's stroke.phuk72 wrote: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.
