CDD uppipe fitment issues

[JHolt55]

I'm trying to install the CDD uppipe for an ars 093 turbo but I've run into and issue. It's bolted to the exhaust header but the flange to the turbo is twisted so it won't line up.

I've tried loosing the nuts on the header but it can't mount any other way than flat with the backing plate fits.

How are these supposed to fit?

Maybe you'll have to call them and see what they say. If there's a manufacturing issue, they need to know about it.

When I installed my turbo, I bought a IDIOT up pipe - the CDD units weren't available back then so my kit came with the ATS cast units. However, I think the installation method i used may work for you as well. I installed the turbo flange bolts loose with the turbo loose. I think installed the oil return / pedestal loose, and the exhaust loose. Only after I was able to get all the bolts started, did I start tightening it all down. You might be able to do the same on your truck.

I would have to say its an alignment issue with the tube and the welds, I know I found out the fun way that my Idioit pipe didnt quite fit, and he builds them bolted to an engine. I had to shave a nub down on my intake manifold for clearance.

I tried it again with everything loose and I was able to get them started after reclocking the turbo and moving the upper around unit it lined up. I think when I took it off at the first attempt is loosened up the flange that mounts the the header and it had a lot more adjustment now.

Another issue I'm having is with the downpipe elbow. I order their wastegate delete flange and downpipe but the flange doesn't appear to be sealing correctly on my turbo housing. Anyone got a recommendation for this? I am unsure if soot would seal it up if I just run it like this.
