Yeah I wanted the exhaust tips coming out the back. It took some work to put a full 3 inch exhaust in there with the narrowed rear end but it all cleared. The key was the fuel cell in the trunk rather than a gas tank hanging down under the floor.

I'm not sure about running it on a chassis dyno. I've never had any luck running automatics on a chassis dyno. The numbers come out weird and it causes confusion. I think I'll just drive it on the street for a while to get comfortable with it and then take it to the track next summer for a few passes.
