i have noticed my truck is starting to whistle out of the pipe more.. its stock exhaust. its an 04 and it has 55xxx miles on it. is there any thing to worry about? it doesnt whistle like an 03 though...

the thing is it sounds ok 99% of the time. maybe once in about 3 months it will whistle more just casual driving
