One other thing I thought about - maybe you'd know Jr or bill, is if I could use that small hole intended for a built in wastegate on the exhaust impeller housing? That way I make my downpipe with a 3" pipe, welded to a 1" pipe that branched off a little to attach the wastegate, and then reattached to the downpipe further down. Basically - could i not run it off the J pipe and instead run it out of the housing hole designed for internal use, it is before the impeller.
