ok so ive read some other posts on here and well seems if u think the cat is the problem u replace it.... well i didnt really have bad performance (or i havent noticed it) but it does glow red, sooo i replaced it. the next day im drivin the car kinda hard and still the cat glows. anybody know why this is happening? also i really dont wanna go to the dealer cuz i just feel like they might be dicks cuz i have a custom intake and exhaust.

 

They cant be dick about your intake or exhaust. it has nothing to do with your CAT.

Know your stuff, stand against them, thats what I did.

If your cat is glowing red probably too much fuel going into it, rich mixture ?

 

could this be becuz my intake ???
