*HEADS UP ON HOGZAUST*
At least in Missouri theyre phasing in emissions inspections that include checks for exhaust leaks. The tech runs his hands along the length of the exhaust feeling for escaping gas. If theres any, the car is an instant fail. Hogzaust is in and of itself an exhaust leak. They will however pass your car if you wrap it with some heat reflective tape, exhaust wrap, and hose clamps, so if you're getting your Hogzaust cars inspected, check your states test for this and wrap the muffler flange.
