those AMS have the same exact type of collector as the stillen shorty, since I havent seen how the primary merge together on the AMS, my opinion stop here but knowing they look pretty much the exact copy of the stillen , I would suggest to look at something else.

the Momenton have way more efficient merging primary in the collector and is also going smothly to the flange to optimize the scavanging.
mandrel bent is also a must but a proprely welded tubbing can do pretty much the same job.
