    I just bought one.

    In reading the forums on this subject I am sure people will probably say "U SPENT $320 ON A $40 PART!?!?!?" But let me tell you about the reality of those $40 parts. Before I begin, I'm not going to get on some soapbox about supporting the U.S. economy or "innovators" because I don't care about that. I care about the bottom line as much as anyone else. It's just that at 40-years-old my bottom line includes time and headache / brain damage along with the money.

    My problem is that the first Ebay housing I bought came with both flanges warped- A LOT. Returned it. Refund received. Time wasted. Second one I bought used after asking if the flanges were flat, got it and the flanges were fine but the welds had separated from the pipe, you could see daylight through the seam. That guy worked with me. Decided to take half a refund in order not to have to send it back. Time saved, money wasted. Deciding not to waste my ****ing time trying to figure out what Ebay housing is one of the good ones, I just went for the real thing.

    The other benefit of the JM Fab is it has studs like the original. These Chinese "engineers" have never seen a DSM. They've never worked on one. They don't know that back fastener sucks to deal with if it's a nut and bolt. DSM guys change parts more often than underwear, it's better to have a setup that comes apart and goes back together easy.

    In the end I can at least say I at least tried the Ebay way, but ultimately it was not for me.

    Just installed mine yesterday. Really tight fit for wastegate but it’s a quality unit. You’ll fight with the dipstick tube

    Mine is just a recirculating style. Their design is pretty compact compared to some Ebay units, that being said my car had a T4 with full 3" v-band discharge. Needless to say, the dipstick tube, and a bunch of other stuff has been fought with and they lost.
