Below is a copy of a post on V-Twin Forum made by "TroyL" from Orange County CA on 2-22-07. Troy owns a 2007 FXDSE and he loaned his bike to Vance & Hines so that they could test the new Big Radius 2 into 1 pipe on a SE Dyna 110 cid bike. Here is what he said:
"I held in my hands today a Big Radius 2-1
--------------------------------------------------------------------------------
I did the tour today at the Santa Fe Springs Street shop. It's actually a huge manufacturing complex with everything! Really great people!
Anyways, the pipe is awesome. We're walking by one area and the gal giving the tour points something or another to the left side as we walk by. I spotted one on a table in front of some office, so I scooted over there. It was the prototype they used for all the publicity. There weren't any header heat shields so I could still see the welds they left and there was a falsie baffle in, but it was HUGE! I haven't seen a Fatcat but this one looks bigger than the pics.
So, we get to the dyno room. They had just finished with my bike, so I didn't get to see it on the dyno, but I did get a chance to talk to two of the wrenches running the dyno. I've got a bunch of info, but the relevent stuff for this thread is:
BR 2-2 106ft/lbs and 93HP big low end flat spot
BR 2-1 110ft/lbs and 96HP perfect
2-1 Pro 109ft/lbs and 97HP very small low end flat spot
Python 2-1 (no baffle) 109ft/lbs and 96HP very small low end flat spot
They did these pipes with the appropriate FuelPak setting, all on my bike. They also verified that the BR 2-1 is quieter than the 2-1 Pro (by 1db)."
