External wastegate. Exhaust manifold or O2 housing?

[DSMunknown]

To add my .02 into the fray.. I just completed my latest round of upgrades along with ERL's Cast Stainless T3 manifold (which also comes flanged for Mitsu or T4) and I am pretty friggin happy at the ease at accomodating a proper 3" O2 housing/downpipe without that Tial44 whoring up all the space down low.

Haven't datalogged yet, but on a preliminary run (minus the MBC), 15psi came up fast and was rock solid thru 3rd gear. Dump noise was also suprisingly less than my old O2 mounted Tial44 setup

^^ Nice John. Does that WG return tube include a flex section? Hard to tell if it may be closer to the DP.

The dump tube is the same one I had on my O2 Housing External setup. Bruce (oldman) recently sent me a section of flexible 1.75" SS that I will eventually use to tie into my downpipe. Right now it's shooting down thru the large space btw my DP and turbine housing.

FYI.. that pic was taken prior to running and all clamps were loose on the Tial44. I could effectively turn it 180* and shoot flames out my hood if I wanted
