I do not smell any exhaust and they exit behind the rear windows. If your moving, all the exhaust is behind you. If your stuck in traffic, there is nothing you can do about the guy in front of you or beside you.
Hmmm, just to play devils advocate, doesnt a muffler shop charge more money for a rear exit exhaust sytem with all the bends, hangers and installation?
