Actually, I am on my second IAP manifold, I found a problem with the fitment of the first one (runners didn't line up perfectly with the exhaust ports) and so I told Marc about it and got a whole new, upgraded manifold, which configuration and build is now the new version they put out for the KADE

So, while I have a DE and know the fitment is perfect, I cant tell you about the E. I also cannot compare it to any other KA-T manifolds as this is my first. Also, if you do get it, check with Marc about which turbine housings will work, I had to switch from a Garrett 4 bolt outlet .63 a/r T3 housing to a precision turbos 5 bolt outlet .63 a/r T3 housing because of a clearance issue with the bmc. I dont know if this is the same for the KA-E manifold though, so make sure you know in advance
