Body:
The car indeed does have a single exhaust w/ a Y-pipe coming out the backside of the (single) muffler w/ dual chrome tips.
I'm no expert, but seems to me like this car has more than 160 horses though. She chirps 2nd w/ an automatic and not pushing it too hard. I posted a couple of pics of the engine bay - they are blurry, which is why I didn't post them before. Perhaps this will help clear this up.
