I hope Sikky knows about it and they probabely somewhat do know but IMO how can they fix it now? They already made 50+ headers and probabely sold most of them so I don't think they be taking back say estimate of 30-40% of them that have quality/fitment issues. All they could do now is make the next new batches better with no flaws. This is why I usually never rush into aftermarket parts that first come out unless the company was big and known and well reputative. No offense to SIKKY but I've never heard of them til these Headers came out. Anyhow the first generation makes of aftermarket parts usually have all the flaws in them. This is why alot of aftermarket parts comes out with different versions like version 1,2,3 etc...they always end up making them better. To me Sikky's Header seemed rushed into production. R&D was only 4-5 months? Any modding company can make a header but perfecting it could take years.
