Z3 35i N54 Downpipes

In the UK we don't have a lot of options for downpipes... I just wondered if anyone has tried the downpipes from Alibaba? Have heard from a lot of people that you can get some quality bits that just aren't branded!

Have also heard 135i/335i downpipes can work with some chopping and re welding?

Happy with Stage 1+ but I know Stage 2+ is what I really want

First thing i noticed was that there are different downpipes on the pictures... on one there are more welds, on another 2 there are less... when i compared these pictures with VRSF pictures. The one with more welds looks like z4 downpipes and on other 2 are maybe 335i/135i downpipes(under car and in the box pictures). So this is confusing...

On some thread i read that cheap downpipes may not match up with the exhaust and flanges are 90 degrees off... so need to cut and weld.

Just google "cheap downpipes e89" and you will find that thread. Cant link spool street forum for some reason.
