i start my car and it will shoot rusty water out the muffler im runnin flowmaster stock application, if i rev it it has alot that comes out, gettin pretty mad tho bc it wont stop- been doin it since i got my car like 3 months ago i havnt drivin it yet on the street but i been startin it and workin on it and upgrading the whole car with new parts everything is running great but i still gotta get a muffler bc the muffler on the car is like 4 yrs old the recipt says so i am guessing its rusted inside and has water in it mabye if anyone has any other suggestions let me know thanks,

 

well all cars produce water when they run, it is a byproduct of combustion. If the car hasnt been run in a while is probly not been run at operating temperature...let it warm up see if it stops...

 

Your muffler or the exhaust piping is rusting out. Most exhausts rust from the inside out.

 

when the car is warmed up it dont shoot out as much but when i rev it to like 3g it will shoot out it was dark when i first tried it a month ago ( it was sittin for a while the car like u said ) (like 6 months it sat ) then i got it and been redoin everything on it since - after like 3 months its gettin light brownish rusty lookin -now better then that dark mud look when i got it - so i am gonna get new muffler gotta be the muffler bc its old and ill get a new header also im gonna redo full exhaust
