Anyone has any experience with products from GRWA performance?

Found a chinese supplier (GRWA) for e92 m3 exhaust, and I was just curious if anyone has bought anything from them (link below):

It looks like a copy of valveteronic designs or bomiz??

I've talked to them on WhatsApp before for inquiries.

Seems legit, same exhaust as the other brands. It's roughly $950 shipped.

Here's a thread with some more info and a video from someone who bought a valved set up from them: https://www.m3post.com/forums/showth...1686392&page=2
