I see where I left out some details...
They follow the same route under the car. The exit side in the rear is different as I mentioned.
If you bought a 'bolt-in' kit from MSA I'm not sure where it bolts up to. Obviously the turbo exhaust exit at the engine will be different than the non-turbo. The owner will need to figure that one out. Some of MSA's kits are cat-back and you may need a new or different catalytic converter.
On the other hand, the 1982-83 non-turbo exhaust exits out the rear left just like the turbo muffler does. So maybe it is a non-turbo exhaust but just for 1982-83 only.
