don't know about bov, intercooler outlet is slightly more angled. turboback will bolt up. you will get boostcreep without doing port and polish of wastegate or boost controller. i suggest catback only, new dual vent bov, and do port and polish or wait for engine management.

I highly doubt that the HKS downpipe will cause boost creep, as it provides more backpressure under high boost than pretty much every other downpipe.
