Thanks again for pointing me in the right direction.
I got my exhaust mounts yesterday. WOW are they rigid. But that is exactly what I needed. You are right, the rear two make most of the difference. I ordered 4 of them thinking that if I didnt need them all for the WRX, I could always use them on my civic, that also has droopy hangers. So i guess my civic gets a hanger upgrade. Since I have two left over.
