gotta admit, never seen a good powerflow system.. i have one sat in my front room, not got proper mandrel bends in it and the welds are not neat at all.
My van came with a full powerflow system, from completely different part of country so prob from a different powerflow garage and that don't have proper mandrels either, also has messy welds and on top on that the pipe is crushed slightly on a few of the bends where they have just tried to heat it up and bend it and failed badly, and yet they felt it ok to leave it like that..
Would defo not recommend them to anyone tbh.
