My exhaust pipes are smoking. some smoke comes out from the very rear but most of it seems to just be out of the pipes. i do not know if this is because oil is in my combustion chamber coming from bad pistons or piston rings or if maybe oil is falling on the pipes from a transmission leak. They just smoke too much so I cannot tell.

What is the question? If oil or transmission fluid are dripping onto hot exhaust parts, it is the leak that needs to be addressed. Besides being a fire hazard, the transmission can be seriously damaged from slipping if the fluid level gets too low. Low oil level in the engine will result in low pressure when the pump starts sucking up air, and that will lead to pistons scuffing against the cylinder walls, and the bearings being torn apart.
