After looking at some of the Karma photos online. I realize half of them do not have exhaust pipe showing (looks better in my opinion). Are the exhaust pipe cutouts an afterthought?
As you can see from the photo, the exhaust pipe is angled down and the end lines up with the bottom opening. The opening above is for heat dissipation.A car-spanning cast aluminum front subframe cradles the 2.0-liter turbo-4 engine. There's nothing in the central tunnel but batteries, so the entire exhaust system lives in front of the firewall.
After exiting the turbo and catalyst, the exhaust dumps into a central muffler before splitting in two, with each half flowing through another silencer to exhaust pipe. The dual exhausts exit from a cutout low in the front fender, ahead of the front door and behind the front tires. Each front fender sports a small grille opening directly above the exhaust pipe to help expel exhaust system heat.
This is one of the concept vehicles. You can also see illuminated side mirrors and possibly drilled rotors.Try this photo. Look at the exhaust pipe compared to your Karma. I think the lower cutouts in our cars are afterthoughts.
