Exhaust tip has white/gray residue...

I notice that after I run my car really hard, there's some white/gray residue all over my exhaust tip as well as around my rear bumper area. What is that? Am I running too rich or too lean or is there something else wrong? Is my muffler getting too hot?

That is usually an indication that the car is running lean. Is it supercharged?

You may want to find a way to increase fuel, as grey/white residue in the exhaust is great on N/A cars, but could lead to detonation problems on S/C cars...
