Cheap downpipe question

Hi guys,
I've found some cheap no-brand downpipe for the M6.
The cheapest (~200/~220$) are just made from pieces of stainless steel soldered together.
People reported that the downpipe have a good fitment and the quality is fine.

Some branded downpipe (and a little more expensive ~300/~330$) have the flex-coupling element that allow the downpipe to move without transmitting vibrations to the rest of the exhaust system (sorry I don't remember the technical term of this piece at the moment).
The same feedback was reported for this type of downpipe.

What do you guys reccomend from personal experience?

The original catalitic converter doesn't have any flex-coupling element, nor the rest of the exhaust system.
It seems that a down-pipe with the flex part allow for simple installation because you can move/slide/turn the thing just a tiny amount to help the fitment, but as said no one have complained about the fixed design.

Just to be completely clear: I don't want to spend over 500/550$ for a couple of stainless steel tubes. Company out there that produces downpipe and exhaust system seems that correlate: M6 owner = dumb people with a lot of money to spend for aftermarket parts.
