White deposit around exhaust tip

[KS9495]

Have a bone stock 08 Busa except for a BMC race filter & X-Tre
I've notice white deposits around the tip of the exhaust after a hard ride
Some have said that I might be running lean & to have it checked
I have only 3000 miles on the odometer

Any inputs appreciated

It can also depend on the fuel additives they use in you region.

Agreed. I believe your fuel may have higher sulphur content and this can leave ring on pipe .

have the plugs pulled if they are white then there is your answer

White is good, means your Lamda and ECU does what it's supposed to. Black means you are running too rich.

Race gas will turn your exhaust white also...
