EYE POSITION DETERMINES EXHAUST PREFERENCES, SAYS RESEARCHER

A noted research scientist, who estimates that he became noted about eight years ago, claims the positioning of a person's eyes on their face directly correlates with the placement of exhaust pipes on the vehicle they drive. According to Dr. Saturno Yipes, a professor of Advanced Physiognomy and Anatomy at the University of Lower Cheesequake in Lower Cheesequake, New Jersey, the... uh...what was I saying?  

Oh yes...Dr. Yipes claims that those with eyes set closer together typically own vehicles that feature paired or "shotgun" dual pipes, while those whose eyes are farther apart favor separated pipes, one at each rear corner.

Dr. Yipes provided the photographs below to help elucidate his theory, whatever that means.

or "shotgun" dual pipes

"This fellow was an interesting study," said Dr. Yipes.
"Over the years, his eyes migrated toward the sides of
his head, like a flounder's.  While this was occurring,
his preference for widely space exhausts, like those
pictured above his head, became stronger."  

"This Lexus IS-F owner prefers his car's diagonally-stacked exhaust pipes, said Dr. Yipes." "I really felt sorry for him; he's never achieved his dream of looking through binoculars."
