quick question, My sister is buying me a CAT CONVERTOR as an early birthday present For my evo. I wanted to know what is the stock cat calaytic on the evo 8? i've seen on other sites where the calaytic is 3" so i figure it's alot bigger than stock. I have a downpipe and a cat back exaust . Also i know it's illegal to have a delete calaytic but will they know? i wanted to be safe so i'm getting a 3" calaytic, what i really want is the delete one but don't wanna get in trouble. I heard it's louder with that on. Also is it gonna be louder with the 3" calaytic on my car since i already have the other stuff . thanks in advance .... For those who have this 3" calaytic how is it?
