Don't GIVE UP! I THINK you should collect the runners under the car, not as they pass the steering column. This is a common type of header in hot rods.
This will allow your shop to arrange the runners on the driver's side to get around the steering column, THEN collect under the car.
In other words, the runners can be arranged in ANY LAYOUT- they can be a long, curved row, 3x1, etc as they pass the pinch point. It can be done with very little, if any impact on power.
Frankly I am surprised your shop didn't see this coming. This notorious pinch point is THE ONLY reason long tube headers are not made for this car.
Yes it's tight under there but there is room for the whole thing with a shop like this and the engine out. Make sure the other side collects at the same location across the car.
You can do it!

Here are the dyno results:
There are some problems, and I have some questions for your guys who know better than I do, I'll address them in another thread.

What mods do you have done at the time of that dyno?
I just ran mine today at 3900' elevation with Kleemann headers/downpipes, Kleemann ECU tune, primary cat delete, resonator delete, x-pipe, and drop in K&N's. Max HP 313.51, and max torque 323.88. My secondary cats may be partially clogged as noted by the dyno operator with a slight ammonia smell after each hard pull. So now I may be looking for a set of 2.5" high flow cats. The dyno operator offered to let me re-run the car if I get the cats replaced, just need to find a good set, and a good welder to install them.
Take care.

That helps answer the question. Thanks illest.
I might run it straight for a while, but I really like the sound of the Magnaflow

I know mine might sound a little different, because our total exhaust systems are different (I'm not planning on running race cats)...
