I WAs WArming UP My Car, And SOmething made me get down and look under it, and i seen that the catalytic converted was glowing red at the end where the 3 inch exhaust pipe begins, what should i do? replace it?

 

Sounds like it might be running lean.

 

yes you must replace it but first fix what caused the problem so you dont just **** away the new one and running lean could be the problem

 

sounds like your cat is deffenitly gone. but before replaceing it , you got to find teh problem that casued the cat to go out in teh first place, other wise your just gonna waist your money on a another cat, check you H2 sensor. and your iem sensor . have you done a error code check yet?
