a cover for something is hanging on the bottom of my car. Should i get it welded back on or should i just take it off. Its hangs on the ground and it makes a lot of noise.

I think a better description or photo is in order here.

i think its called the catalyctic cover...

um you cant take off your catalytic convertor

you could, but it would be illegal

most likely your bracket has come undone which holds the cat up

Or the cat heatshield? The one attached to the underside of the car, or the one attached to the cat? You need both.

its not the actual converter its the cover of something thats hanging under the car in the mid section of the car.

Hanging from the car or the cat? What does it look like? What'* it made of, what'* it attached with normally?

PLEASE be more specific.

its the cover attached to the cat. The guy at sears told me that it'* okay to rip it off but i dont trust him

Your instincts serve you well, young Padwan. That heat shield is there to prevent you from igniting brush fires when you park over grass or weeds. Go to an exhaust shop. They should tack it back up for you for about $20, if they even charge you.

u think its gonna be alright driving it cause it skids along the ground.
