First, I am looking at bolting a glass pack right up to the stock cat. does anyone know what the size of the flange is there?
heres the glasspack im lookin at:
if that fits, I want to kno if my truck will pass MA emissions with a glasspack on since im still plannin on running the cat?
i would keep the stock cat-back as a backup incase i need to attach that for emissions testing
