[quote name='flash' timestamp='1396892947' post='156644']it is a really odd phenomenon that i have noticed. not sure what's going on there, as the length should be reasonably fixed. material expansion should be minimal. there are no soft couplings at play either. nonetheless, i have noticed it too.
another "eyes playing tricks on you" oddity is how far it looks like it's sticking out, dependent on your angle. looking straight down, it's very easy for the smallest protrusion to look larger, due to the angle of the bumper cover
crazy how much time and energy we spend on something as silly as an exhaust tip.[/quote]
Funny you should say this; now I'm paying attention to every car's friggin' muffler tip to see how it's positioned, how much it sticks out, etc. LOL. So here's the odd thing I saw today in our company's parking lot : a dual exhaust tip Lexus IS ( don't recall the number - 350 maybe ) with one tip looking as if it was sticking out just a bit more than the other. So I thought it's clearly the angle from which I'm viewing it , so I got right behind the car where I estimated was dead center, less than 3 ft away, and one still looked a bit different from the other. Optical illusion I said to myself. But being the OCD guy that I am, I went up to my office got two rulers, placed one vertically against the rear body and the other on the tip(s) and the. measured both tips length from the body. There was no optical illusion, one tip was out about a 1/8 " more than the other. That was a surprise ! ( and the bigger surprise is that I could see a difference as negligible as 1/8 " with the naked eye ) .
