You can see in the valve bodies that they're clamping stainless steel valve bodies to the titanium piping instead of using a casted titanium valve body. This is one of the cheapest manufacturing techniques and your valves will rattle. Maybe not immediately but overtime they will. if you want to take the risk, you are more than welcome to do so, but we have had so many people who order systems like this from suppliers and they receive something totally different and their credit card companies are unwilling to assist and aliexpress sides with the manufacture and they end up being forced to dispose of the system and purchased the authentic thing as they are embarrassed to have their valves rattle.
Remember, if we were just drop shipping systems like this with no engineering developments, we would've failed long ago.

I’m with others about the midpipes. I can’t risk the noise limits at my track to buy the full system, but looked at the Dinan mid xpipes for M5 which needs modifying for F92 and not available until March 2024 which really means August 2024. I’ll buy as soon as you say the word
