Hi PaL, welcome from alt.autos.fiero!
I see now what you were saying about the exhaust. I would recommend that you replace the exhaust with a stock configuration as I don't see any way of using your newly purchased cables with the exhaust pipe routed that way.
Here's a picture of my '88 6-cyl exhaust, it's somewhat different than your earlier 4 cyl exhaust but the general layout is the same:

Here's another thread that discusses exhaust support and design issues:

Note that the '84-87 exhausts interchange from the downpipe back, and the '88s are unique and won't interchange with the earlier years. Also, you can swap a dual exhaust from the V6 onto a 4-cyl car really easily. In all years the V6 was only a dual, and the L4 was only a single exhaust.
In your case I would recommend getting a used but good condition exhaust system with all the springs, spring brackets, and hangars. You can bolt the whole exhaust on without removing anything significant.
