i want to get a borla exhaust but also be able to run open headers so im gonna look at a cutout....wont this screw with how the car runs if the pressure keeps changing?

also how much of a hp difference is there between a stock exhaust with borla and true duals(h-pipe and bullets)?

long tubes with a catback flows more the optimal for a stock motor LT1

no need for a cutout
it will hurt you
