Or do you already have an idea if this will not work as well as the available midpipe/Super Q for a street/touring PRHT??
Thanks for doing all the R & D work once again!
If you are within miles of stock the bigger 5 inch body converter won't really show results for you, it's really development work for the boosted and 2.5 conversion crowd, and it will cost more than current standard midpipe (best guess today is $100 over our standard midpipe). One of the interesting things about the helmholtz is that the further up the system the helmholtz can do it's job, the better job it does. So, we actually need bigger version in the muffler area to equal the current Helmholtz Midpipe that already exists which is amazingly effective, and was tuned in my wife's 2012 PRHT. So, if not adding turbo or 2.5, for a PRHT our current street header with helmholtz midpipe and SuperQ is the popular combo and I don't expect new options to be more effective or cost any less for the full combo (particularly since new options must be quoted with higher materials costs thanks to Trump's trade war which has spiked costs on all metal raw materials by big percentages). Moreover, all the tooling for existing parts was paid off years ago.
Thus, assuming you are normally aspirated 2.0 the only thing that might really be tempting here for standard 2.0 street customers is option for putting helmholtz at the rear if either the Helmholtz RSII or Helmholtz SuperQ makes it to market, that will make the install just a bit easier than the helmholtz midpipe that some less experienced customers find challenging simply because it is stuffing so much into the center tunnel. But in terms of effectiveness per dollar, I don't expect the new bits to beat current system actually developed on the PRHT in particular.
