The collecter area needs some cleanup work, the worst part is the rest of the welds are good, granted probably done a bit too hot, but good beads that flow nicely. Given how the pipes are cut they put a lot of material around the collector area. I will clean it up myself given that I have to enlarge the ports anyway because of the head work.
As far as where the welds meet inside the collector they are smoother than they appear in the picture.
As for your manifold James it looks like there is a different piece design on one of the primary tubes, like it bends one way and then another.
I personally don't feel like any of this will affect performance the bulk of my gripes is cosmetic and it deals with the work in the collector. As stated after a gasket match it does not really protrude into the gasket area, that is how I determined it shoudln't affect flow.
Don't worry about saying what you think, it's why I posted pictures. Not going to hurt my feelings anyway.

You suck Wes !!! j/k
I full agree on the performance issue. Unless you are REALLY pushing for big numbers the header should be the least of your problems. I was just noting the fact that it doesn't seem to represent the quality that Hotshot seems to be {allegedly} known for.
My first thoughts were about the collector as well, thats why in my album I have that picture with my finger in it to show how there are these pockets that affect the flow... Hard for me to grind them down... HS said that the removal of the welded piece inside didn't make that much of a difference in power and it was too much trouble to put it in.
Originally posted by wes After all this time I received my manifold from HS today. It is a nice piece, welds look good overall. Not extatic about the turbo flange but I gasket matched it to the T28 and it lines up pretty good. WIll have to clean it up a bit. Here are the pics. FWIW I have an extrude honed T28, if I had a standard T25/8 exhaust housing I would not have to port the flange out at all, so despite the appearance it will flow just fine.
bet it doesn't look as bad in person... lighting and camera angles can be deceiving and not very flattering.... but from that pic it could have been cleaned up a little
Originally posted by myoung a collector like that is a 100 times easier to weld than an entire manifold...
true, but i could also post pics of manifolds that are more difficult to weld...that have nicer welds(welded by ffgeon). but thats not the point. point was to display some nice merge collectors for comparison.
i agree with se-r57
IMO they should purge the inside of the mani while TIG'ing, then those "boogers" would look just like the welds on the outside. but purging uses gas and gas costs $.....
dont get me wrong, its a nice piece but could be better.
If I were to do this from scratch I would have a custom equal length manifold that used a burns stainless merge collector. Something that mirrors the FMAX manifold for the SR20. I would basically take Aaron's turbo setup and put it on a GA16 with built internals.
I thought about doing something similar with only the T28 but I couldn;t stomach the $2,000 to have someone build a one off manifold like that. We can dream I guess.
FWIW this manifold will do just fine. And from the looks of the picture my flange is more open than James, compare the distance from the edges of the opening to the bolt holes on the 2 pics.
I wish I had more welding knowledge so that I could build my own manifold, that I am working towards correcting.
I made my own 4 into one collector out of four 45 degree elbows. It didn't come out half bad for my first attempt. I used a mig welder and schedule 40 weld els.

i've got 2 stainless b14 2.5" exhausts in my garage....hehe. one exits before the passenger rear wheel, and the other is a full cat back. i'll post some pics later.
the thing is guys, I had the CA model so I put the cat in a different location... I don't know if I can just throw any old exhaust on there and have it work.
I agree in some ways.
