There are two correct ways to vent the exhaust for a vehicle. Side pipes and under the rear bumper.
The lines are so much cleaner. There is no interrupted look. Don’t even get me started on cars that have an exhaust tip on one side. Just hide the thing!
This has been you semi-regular PSA on what is the correct configuration for exhaust tips.
If the images get screwed up it’s because of Kinja. My sacrifices where apparently insufficient.
