I hope none of you live in San Francisco...Looks like the bay bridge is getting the same quality!

Chinese steel will be as good as you specify it.
M-Tuned rods are made in China are they not? They don't break because the metals specified are of the correct standard.
Just saying Chineese steel is ---- is a gross simplification. If it did indeed suck, they wouldn't be able to build bridges that span 26+miles and have the worlds fastest growing economy etc etc.

I cant believe I didnt see this thread earlier, I think I was the only person in EXISTANCE that had a good "S4 style" single runner 100 dollar ebay manifold that lasted, and all that turbo weight was pulling that ****** down with its homie gravity... now it is lost in the mail somewhere, probably cut up and welded in some raped position on a UPS employee's civic.

@ giblets, Ebay sometimes is ok as long as the part isn't coming from China or a cheap company. You will sometimes find trustworthy sellers for car parts. I have a brand new turbo and manifold I had bought for myself from Precision but it looks like I'm not getting my car back together for a while. You can't go wrong spending more money on a great quality part that won't make you wan't to pull your hair out like with cheap ebay parts.

Exactly. Reality is there's cheap steel and there's expensive steel. I worked for a metal company and we were able to get cheap American steel and expensive American steel. Guess which they bought for us... the rusty crappy cheap steel that had imperfections and hard spots and surface rust nearly 1/4" deep all over it. I can count way too many times where we have gotten a round 5" piece 2-3 feet long and it has literally cracked in half on a hard spot. I can also say I've worked with an expensive piece of steel that cuts like butter everywhere. Were talking manifolds here and there's 1 main problem with the ebay junk.. the steel they use is too thin. If it was 1/8" thick wall it wouldn't crumple in your hands. Make a manifold with paper thin "American good steel" and see what happens...yes it will also crack. Say it was the proper thickness for the application and it cracks even then.. now you can say it's cheap or not cheap Chinese steel.
It's also true about spotty quality. It would usually take a couple of shipments to get the quality right, but then a couple of shipments later problems would crop up.
No, you can't pigeon-hole the most populous country in the world with one sentence declarations, but there's a reason why I no longer purchase from them.

I wonder how much the collector (runner convergence) at the turbine flange has to do with the failures. Seems like there's a lot more of the quasi-log styles that fail than the long tube style. Flange loads are completely different. The top mount basically sits on the flange while the other is cantilevered off the tube wall.

Wow - the doucebaggery begins early today.....
I'm not some noobie f#cktard - I was getting good advice here many years ago - probably even from you - when I was doing my build up. That's why I looked in the sticky - almost expecting THAT'S where someone might have put the answer to this problem.
All I want to know is if people have found a good replacement which meets the same fitment as the shitty ebay manifolds which crack. I'm sick of welding the f#cking thing up, and don't want to have to rebuild both the dp and manifold. If there aren't any easy options, then perhaps the elite members here might be able to say so?
Otherwise I'm gonna have to pay to have one fabricated locally - and I'm in Australia so there's no point me telling me the details of your local fabricator.

Ebay manifolds are garbage. If you want something reliable look at fm, begi, absurtflow, or other of our vendors here on the forum. From memory those 3 are the common biggies.
There was a diy thread few days ago that was also very good guide.
