Does anyone know about the particulars of the exhaust system? I know the manifold is an integral part of the cylinder head with a single 3 bolt outlet to the catalytic converter. From there is unknown. My questions are- what is the diameter of the pipe from the converter to the muffler (silencer ?) and then to the outside? What is the diameter and length of the muffler? Finally, any information on the make and model of the mufflers (regular and sport) in question? Pictures would be great too. Doing research on mufflers while waiting for my car.
