Dumping the exhaust behind the rear axle?

Thanks for all the replies guys, I am still undecided with how I want them ran. We don't have to pass emissions in Indiana, and I don't have any kids I'm worried about riding in the back seats.

We do have a lot of cruise ins in gravel parking lots and in fields, so dust may be an issue, however I might be able to get away with changing the angle of the outlet.

T/A style may be the way to go. I'll keep you guys updated
