Since I changed from a stock to a more freeflowing muffler i've been getting alot of carbon dust on the back of my car. Is this normal or is there something wrong. The plugs are clean no carbon on them. The temp gauge doesn't quite go up to the middle. Could it be running a little to cold?
thanx

It's nothing to really worry about. all cars do it when they get older. it did it with your stock exhuast too probably, but this one is more free flowing so now it's more noticable. it's normal so no worries. mine smokes and i don't really burn any oil between oil changes and i still get 37 mpg and my bumper gets covered like yours.

This is actually normal but you wont see it being built up in a stock application. The muffler does not exit far enough past the bumper and the gasses are allowed to pass close enough to the bumper to cause depostits, extend your exsaut another inch or thre eand it will fix the problem, or just clean your car more often.
