Hi, I really can't see them being different apart from the diff section.  `performance is quoted as exactly the same, it'd make no sense as its only that section that needs changing or that has changed...

I couldn't possibly imagine why you'd be asking so many questions about Fujitsubo's Legalis systems, or be so exercised about finding out as much as possible about them.

Have you ever considered making and selling your own exhaust systems?

its all in your head.  you post on my threads.  

Why don't we start threads on your exhausts speaking about the following issues with Zstory:

 Lead times, taking money upfront and not delivering for months, having a whole range of reasons why things are delayed, fitting and quality issues, problems with having everything made in China and not having a close enough control of manufacturing, lack of technical information, lack of technical drawings, lack of Dyno development, lack of actual knowledge.

So it looks like 15413 is for an r180 differential and 15415 is for an r200 differential, but the information is so inconsistent from one retailer to another that I am not sure about any of it. I don't know if 15418 is a typo or what. I see exhaust hangers in the illustration and think that's what the brackets in the parts inventories are, but who knows.

Another thing I am finding is HUGE swings in price, from $1,404.46 to $3,299.00, and that is just within the EPU versions.

I reached out to JDM Car Parts but he hasn't responded yet. I have also reached out to Fujitsubo and Greenline Motorsports. Maybe one of them will respond.

I'll email the UK importer and see if they can help.  I'll also try fujitsubo.  I'll place a sportsman's bet on it just being the section before the silencer that varies.  I do wonder why they didn't do it that way initially.

[Matthew Abate]

I think you’re right. I would rather have the split one (15415) so the pipes tuck up better, but I don’t want to order it and find out it doesn’t line up with the twin pipe indentations on the r180 crossmember.
