Well I did it. I spent all day searching through all the threads. Listening to all the sound bites on youtube. Looking at designs, learning about the companys, researching prices and this is what I came up with. For low end grunt, and the deep snarl I was looking for and in keeping with the original Buell under carriage look - it has to be the Drummer SS pipe for the 1125R. The only detractor is the $1000.00 price tag. My second choice (because for less than 1/2 the price $375.00 - $450.00) the HMF,FMF pipes have a good deep low exhaust note and improved low end - but were anti Buell in design by hanging out on the right side of the frame. I would love to have the Drummer but cant depart with that kind of money. I looked on Ebay and other forums but no luck finding a used one or discounted one. I will probibly just go HMF (if I can swallow that ugly side hanger stuff) and try to save up for a year to get that awesome drum beat!
