Do all aftermark exhausts with a deeper sound exhibit sputter while downshifting? I had a Borla on a Vette and it did that and this weekend with Don's Viper which had a Corsa exhaust, it did it as well. I know some people like the sputter, but I don't and was wondering if that was just something that came with a louder exhaust.

Are you talking about the snap, crackles and pops on decel? If so, mine does. If not, I'm not sure what you are talking about.
