Intrest in a sedan center exhaust rear section?

I share your aversion for drilling on a vehicle. It's not worth the loss of strength and the hightened likelyhood of rust. I did have to drill one tiny hole for mine, and made sure it was in a noncritical area.

When I think of a dual conversion for a Yaris, this design seems to make some sense as long as the muffler is small and nothing hot is near the brain.
