I think I know the answer to this but I wanted to make sure because I see alot of turbo back exhaust systems that are 94 and up.
So anyways is the difference between 93 and down to 94 and up that the turbo housing is different due to the wastegate and that an elbow bolts to the back of the housing were as a 93 and older just has the v-band fitting directly behind the turbo.
I think that makes sense
