Well after getting caught up in the vortex of never ending research and possibilities for stage 1 exhaust, I elected to forego the duals and went with the Fullsac ceramic coated sportpipe instead. This pipe is essentially a stock header with the cat cut out and a collector put in its place. Heat reduction is my main goal and just let the motor breathe a bit. As is usual for those of us afflicted with HD "illness"it comes down to: so many toys and options and never enough $$$. My setup will be full sac sport pipe, SE Ventilator, Supertrapp SE Stouts and FL-Vieds-10 for now. Have read about others that are doing same without issue. Should I find differently a Dobeck Gen 3 will be installed. The sportpipe is $399 or $299' if you return you OEM back to them. I have no financial or otherwise affiliation with any of these products or suppliers just what I ended up doing. Be safe.
