DC1, I apologize, I meant to include that, but figured that since I had posted it previously, it might seem redundant. When I first go my RT (the end of October, 15) I was get- ting say, 32 to 34 mpg. but was also trying to learn the power characteristics of the Spyder. Somewhere between 1,500 and 2,000 miles my mileage was around 34-36 mpg. Like you, I thought the Spyder was too quiet, and at idle sounded like a sewing machine, and installed a cat delete pipe, mainly to get rid of the heat it produced, but also for a little more sound. This worked pretty well, sounded good to me going down the road, but at idle it still had the sewing machine sound. It did seem to provide a little more power, and my gas mileage at times was around 38 mpg Around 4,000 miles I learned about the exhaust I recently mentioned, I now have over 6,000 miles on the Spyder and have seen very close to 42 miles per gallon 3 times, and like burning non-ethanol gas. The system is noisy, but not really loud, compared to some sport bikes and cruisers. I tend to ride aggressively at times, and when really getting on the gas, over 5,000 rpm It is loud, but then, that too depends on what helmet I have on my head.
Hope that helps you out somewhat, I am pleased with the system, I think I got my moneys worth. I forgot to answer one of your questions. We, my wife and I, have no problems listening to the radio, but then we do have Sena headsets. I think I can be safe to say, listening to the radio, thru the speakers, is not much different than with the stock system once you get to highway speeds.
