i have a question about the 3way cat(s). i just had a magnaflow muffler installed. i know that it takes time for the muffler to "burn in", but i was expecting a little more of a note from the rear. does anyone know what that cylinder is in the front center of the car? is it a resonator or second 3way cat? i didn't see any sensors in it, so i'm wondering if anyone has removed that monstrosity? thanks in advance.
