Single exit out the "butthole" on rear bumper

On externally waste gated cars (or even internal waste gates), you can either let the waste gate dump exhaust directly through its own exhaust pipe or it can be connected to dump into the main exhaust which is significantly quieter. If the waste gate is routing exhaust through its own pipe directly into the air, it sounds very loud hence the screamer pipe description.
