Invidia gemini dual y-pipe
 

I know this is a long shot, but would anyone happen to have a spare? I only need to replace the passenger side!

Also, if anyone knows for certain whether any other brands (e.g. CNT, MXP, etc.) y-pipe would be compatible this information would be very helpful so I can expand my search.

I was able to get the replacement from the manufacturer.

Thanks to Invidia!
