Dumping the exhaust behind the rear axle?

Hiding the pipe behind the bumper is a good idea also ... I like that.

I didn't hide it, lol, it's just terminates right at the bumper, instead of sticking out.



Dumping them before the axle may increase dust and noise in the car.

Exactly the reason I switched mine, it would stir up a dust bomb on dry days. Sound wasn't bad though.
