Like the round trumpets myself, your eyes go to them, as they are diff than other lines of the car. Also they add great bling in a low keyed way when polished.

Interesting options, I like the mental exercise and generally I prefer geometric and angular designs, but having browsed all the options presented here... while I find the actual photo of the two angular pipes would be my pick amongst all the optional designs, I find the "as shipped" round exhaust tips the most appealing, no contest.

Here is a question to those of you that prefer the round tips. If the car had come with these angular tips would you have excepted them as part of the new angular design exercise that the designers seemed to have in mind for the rear / rest of the car?

No I don't think I would looks too much like the exhaust Cadillac is putting on their cars.

dunno, it did not, so I won't speculate how I would feel...

The sound from the C7 brings a smile to your face. I wonder how many hours GM spent on the exhaust system and if the round pipes were needed to obtain the sound. I wouldn't pay the grand plus for the 5 horses but enjoy every dollar of it for the sound!

I like the exhaust shape but I don't like the look the added white gives. I would have left the lower black.

That is actually a really good point about the resonant frequency and excited modes of the acoustics being a function of the shape of the pipes. They still could have hit the same frequency with a rectangular exhaust, but the dimensions would have had to change, and the exact mode would be different. With round tips, the modes are based on Bessel functions; with a rectangular shape, they would be sine functions.

We just finished up the install of our prototype tip. I agree with the very first post. There is absolutely nothing rounded on the car, why round tips. Seems dated to me. So this is why I decided to take matters into my own hands.

Wow! Some folks on here are clearly way smarter than me! ;-)

I think you did a nice job on the design of the prototype tip. However for me, the NPP round tips imply power while (again just for me) I don't get that by seeing your prototype tip.

After looking at it for awhile I think I agree, but it would be interesting to mess around with that rear fascia to see what different treatments will do for the look.
Showstopper; IMO you need to partition that collector.

showstopper, With your new exhaust tip, does it change the sound of the exhaust?

So, since its angular, anyone think of a bow tie tip? Or would that be too 'truck'?
