If you look at the pics of the kit in my sig!!! The tube into the downpipe is at the very end of the downpipe, about the furthest you can put it away from the turbine. Where it is placed it will barely affect the flow.... Sean is like a ninja master when it comes to building manifolds, his technique is FLAWLESS!!

The 63 surges like hell on a MKIV, I know the flows are quite different, thus up one to to AR sizes on a 7 VS a MKIV, but the characteristics of the turbos after that are very similar. Ultimately, a 63 will flow about 100hp less than a 67. Carl

you would gain more hp by venting but not everyone wants that. I'm sure they have a choice if it's vented or not.
I think the manifold is one of the better designs i've seen (longer runner's would be nice but it's not too practical in the engine bay). As for the DP there are no sharp entry angles (45 or sharper) and it is joined pretty far down. I also think V-bands are sexy

Just my 2 cents

Zero R and Sesshoumaru thanks for clearing me up on that matter. I was just stating what I knew and apparently I was wrong on this matter. I am still pretty new to the turbo world. I try to read what I can on turbos. This is a learing experince for me.
