Ok, thatīs the kind of answer I already expected.. I did some search and found a few topics about the same issue from earlier times. But it seems that there are always people on behalf and against.. Now Iīd like to hear the real stories from people who have experiences of their own..!!! Of course I understand, that better known products are more appreciated, but cheap isnīt always the worse as some may think, especially people who have money to do whatever they want and so on... I donīt for example care if my intake kit is AEM or some cheap product, IF they work like the same, without differences. To save money is a good thing at least for me, in a case when you donīt have spare on quality.. If I decide to order this kind of kit, I will have no interest in sending it back because of a bad quality or what ever, then itīs only a loss for me and thatīs it. At least I can try to sell some of the parts forward then... But isnīt it so that for example Greddy dump valve is quite known product? And Garrett turbochargers? Those include on that kit.. For example headers didnīt have any mark on it, and people have had mostly problems with those, I think? It sounds that some of it might be good and some bad.. Iīd like to have enough reliable information before I do anything! I wonder the amount of positive feedback that the seller has, it canīt all be crap then? Please, tell me if you know!
