Well, what do you think Clark Kent would say if you wore a big “S” and a red cape? Yeah, in my view, “poser” pretty much describes it. No, it’s not the end of the world and I doubt anyone will be so gauche as to laugh out loud, but Porsche enthusiasts will know. To me, it is simply trying to look like something you are not; it’s a bit phony IMHO.
I personally like the oval single exhaust found on the regular strength Box. It is a uniquely distinctive feature and one that has caught my eye for years. Aesthetically it really works. It is what the designers at Porsche decided to go with when they built the Box. To borrow a phrase, consider it like a scar in fine leather, proof of the car's authenticity.
I doubt there is any difference in sound between the two tips.
There is no power or breathing enhancement, it is simply distinguishes the S from the non-S.
That's how I see it from my knothole. Sorry my opinion may go against the grain. Ultimately, do what makes you happy.
(Now, pretending your car has special colors is the mark of a real poser!!
