air silencer
 

i am curious if i take out the air silencer and if i dont put in the cold air intake thing or whatever would it do any damage to my mustang i have a 2000 mustang and also does anyone know if it will affect my warranty thanks

Well to hop up my 4 popper I took the silender out and the car felt a little faster. You'll have to watch out for over heating, after you've driven the car a while and you park all the warm air trapped under the hood will get sucked into the intake and make your car drag and struggle to stay started. Also if your driving with it off dont hit any puddles.
I'm not sure if there are any long term effects but I would recommend replacing the silencer with a cold air intake or something.
