A few years ago, a bunch of badwebbers got together and conducted a fairly intense exhaust shootout for all of the easily obtained US XB exhausts. Prior to that test, the data that was present was all on different bikes, different dynos, different operators, different altitudes, different weather, etc.
Terry at JT&S and I have been talking about doing that same testing for the 1125 market for some time. We've locked down the date for doing it in approximately 5 weeks on the JT&S dyno in the days just after the AMA races conclude there on May 16th. We have a bike, we have the room, we have discussed the test plan but haven't written it down yet. It will be similar to the XB testing, with a few changes:
1) The XB testing was for both an XB9 and an XB12. This will be using a single 1125R only.
2) The sound testing in the original XB test was a bust. We had some setup problems, and determined that recording sound in a dyno room is pointless, as the dyno drum/tire noise is too prevalent in the actual sound files. So we’ll set up a drive by mic and capture the sound in the external environment just outside the shop.
3) We should be able to use the EBR tunable race ECM for fueling correction. But we’d probably swap the stock ECM in to establish how far off the pipe runs on the stock map with AFVs set at 100
4) This will likely be limited to slip-ons only, as we won't have time to do the engine pivot to mount up full systems.
I am going to contact all the exhaust manufacturers over the next few days to see who wants to play. For now, please respond here and tell me who you'd like to see contacted. If you have an email contact of someone at one of the manufacturers that you have communicated with, please provide that to me. I don't know how many of the European pipe makers will want to play, but I'd guess most of the US ones will. If one or more manufacturer won't provide a pipe, we'll see what we can do to scare one up somewhere, but we don't have a lot of time to get this prepped. I suspect most will want to participate, as it was GREAT publicity for the players in the 2006 XB test.
I'll start a short list, please feel free to add:
