Doc, that was more-or-less my aim. The Magnaflow I put upstream is 2 glasspacks in one housing-very little cross ventilation. Wouldn't be effective as a crossover. Just make sure the Cherry Bomb will do that. The $600 Mag cat-back we all bought is 2 of their $100 mufflers w/tips and $400 worth of pipe.

So that's where I came up with the "Dual/dual" name-just 4 glasspacks.
