So, I got into an argument with someone about how many cats are on our v6 mustangs. I'm telling him there are 2, but he insists there are 4.
So my question is, who's correct?

And a secondary question
Would running a quad exhaust, like that of a boss, reduce drone by any means?
And what about dynamat, does that help with drone?
