The Remus exhaust did though produce a noticeable increase in mid-range torque, so maybe I am quicker through the twisties. And the exhaust note is not abnoxious, unlike some American made stuff, with after market, or even stock, exhaust.
Was the increase in torque actually measured on a dyno, or placebo effect?
I remember a friend on mine that was going to do some hop up work on his Harley. He had a friend at the dealership that ran the dyno and got a couple passes for free with the stock engine. He swapped exhaust, cams, and air cleaner and rode the bike for a few days until he could have his buddy dyno tune it. He was all excited about how much faster it was. First couple passes on the dyno showed less HP and torque across the board than the baseline stock dyno runs. I guess noise ment HP. After the tune it did run better and they did end up with a sizable increase in HP and torque.
Obnoxious is dependent on the person listening to the "noise"!
