There I was about to ask you about "coring" a V4 muffler.
Excuse me now, I may have just soiled myself in excitement...

I googled that for you :
1. Bends always have a thinner outside radius due to the bending process. So, for a given thickness, done properly, pie cuts are stronger.
2. Given the above, you can in theory build a lighter exhaust with less concern over longevity.
3. Pie Cuts allow for nearly infinite radius and direction change.
4. looks badass

If you wanted to post facts, try not to quote the marketing page of the website of the company that supplies the pie cuts.
and as far as point 4, I think it looks like garbage whereas if someone had taken the time to properly bend the tube, it would come across more like careful, well thought out craftsmanship and not the high school shop project the pie cut tubes look like.https://www.ticonindustries.com/blogs/titanium-news/some-advantages-of-using-titanium-pie-cuts
The reality is that they slow down the air flow and can present potential failure points.

This looks like poo. You know why? No freaking belly pan! No manufacturer seems to care in making the bike look as clean as the stock pipes. At least akrapovic tried.
And, where are the maps? Termi has them. Akra has them.
These are $20,000 dollar bikes, FFS, follow through with your products, guys.

good point you should tell Honda that they don't know what they are doing

Of course Honda would do it. It's a like a Japanese signature and part of their culture, like soshoku danshi (why don't you google that) and not one that people who can do better would bother to emulate.

lamborghini aventador exhaust (and about any titanium exotic car exhaust I've seen)
honestly I was originally just joking around , but The exhaust I bought in the beginning of when it became normal options for bikes cracked a lot . In the beginning of their use in motorcycle racing If i remember correctly they cracked a lot of the time which made them cost prohibitive for the street and even in racing they failed too much . Akrapovic has some advanced technology to bend pipes , but if you notice when the bend is past a point they weld sections together.

That's all true. A lot did fail which is why is the point I was making - I don't know why people continue to choose that method for so many applications - but yes, in cases if the bend is too extreme then the pieces do have to be welded. But there's a big difference between a couple of welded sections and like 52.
As far as titanium exhausts in Italian cars goes, here's one of my cars and you can see that we deliberately did not go with 100 pie cut sections. Yes, there are multiple sections but the pipe thickness between the inside and outside on bends is pretty consistent. Also, I am a supplier to the highest level of motorsport (four wheels not two, though) and they opt not to do welded pie cut sections like that. Obviously, it is not realistic to make all bends out of one continuous piece of tubing but, as you correctly pointed out, there are reasons not to do the opposite either.

The exhaust I ordered is titanium and has plenty of sections, but doesn't resort to pie cuts for the bends. I had a Werkes exhaust with pie cut titanium on a different bike a year or two ago and one of the mounting bracket bolts wiggled loose, allowing the exhaust to wiggle a bit. I noticed it immediately, but before I could even get to a stopping point, the exhaust broke at one of the pie cut sections.
Took it to a local welder and he said the pie cuts looked really pretty but made it weak. So I'm not a big fan of that kind of thing anymore.

Carbonvani will have the Arrow system on their 'Tricolore' Panigale V4 at EICMA 2018. It still looks .... despite the bike it's fitted to and their attempts to soften the blow with a custom made bellypan. The phrase "You can't polish a turd' comes to mind.
Not....... Carbonvani will have a particular arrow with the finish of Pagani Huayra's exhaust.... but under engine...
