a couple 45 degree 1 5/8" bends work perfect to bring it back in to the test pipe area. grab 3 tial flanges and you could weld in an angled piece to the exhaust, then put a flange on it, and flange the 45 degree piece. that way you could unbolt it and go open or recirculated.
wished i could make a already welded kit, but no way to do it with all the different exhaust combos out there.

The sound gets old for me maybe because I already have a 3" dual exhaust which is pretty loud all of the time so when the dumps kick in it just multiplies it by so much, also you will get the exhaust dumping out right below you so with windows open you might get some fumes.

Its all relative though, but if you like the volume of your HKS I would say you are NOT going to like the volume of the Open Dumps (2x louder at 6 psi 2.5x+ at higher psi).
Im planning to go with the Greddy EVO TT and 3" dp, hopefully to make it a bit louder, but I also dont want it to be too obnoxious with the open dumps. Plus, like a few people have said, I like the sound of our engine/exhaust tone.

I can accelerate very quickly on spring pressure up to about 9psi without them opening. I run Tial 1 bar WB springs. IMO everyday acceleration isnt crazy loud, my APS TD sounds great, when I want to unleash hell its only a small throttle input away

I am thinking about going with open dumps, and the utec will allow me to keep the wastegates closed until XX psi.
