First of I dont know if this is an ABS or Engine problem. My ABS light seems to come on and stay on some times when I start the car. I also noticed that the muffler system seems to be getting louder. I dont know if could be the vacuum system that "from what I have been told" applys the ABS. If any one has and idea what this could be, Thank you!

 

You have an exhaust leak Thats why your car is loud.

You also appear to have a problem with your ABS system.GEt that **** fixed or you could be in a bad situation and die. Your ABS is electronically controlled, not controlled by vacuum. Who ever told you that is either lying, they don't know ****, or they were mistaken and actually talking about your power brake booster.
