Anyway, what I'm driving at is that even with a stock exhaust (if no secondary cats exist on it) will smell just as bad as an aftermarket exhaust with the AR CDP. There is no secondary filter (cat) to remove the smell... Hopefully someone can chime in though who has this or a similar setup to let us know.
