cut a 1" hole in mani right under #2 runner and got a pipe stick welded on with a flange. had it coming straight down at first then realised it wouldn't bolt up do to the gate hiting off the block so had to get the pipe cut and angled so it would all clear. im using that wierd power steering pump from an 88 shelby z that uses a bracket that is bolted to just the belt side of the block and doesn't have any support bracket that bolts to the back of the block like the more common pump. here are some pics with it off. might get pics of it on this week. it made a huge improvement on my setup. so much exhaust doesn't have to travel the whole way across the mani from number 1-3 when you boost up, just exits through the gate. sounds awesome too. fit with my stock swingvalve and 2.5" downpipe as well.

it was on late last summer with my t3/t4 then surged that to death and got a stock tII and just put this mani and gate back on like 2 months ago. works so good, defiently gave me some more power especially with the small .48 housing and small internal gate hole not getting so much exhaust and chocking the flow. sounds so sweet tooooooo.

Did you say that you stick welded it? what type of welding setup do you have?

i said i got it stick welded. got it done at a local shop. then found out it wouldn't fit and had to cut it and get it rewelded on an angle and as you can see this other shop did some pretty crappy looking welds on that part but it doesn't leak so whatever.
