Dumping the exhaust behind the rear axle?

My 57 Ford had them right under the bumper but you couldnt see them as they were beveled. super quiet inside as the pulses were directed to the rear, not the ground under your car so it can bounce up and be felt in the cab. Im going to run a single exhaust from my turbo 6 out the passenger side in front of the wheel NASCAR style. Dumping under the car, especially before the axle makes everything under there black with soot too.
