Ryan, I've had my stock tapered pipes completely gutted. I couldn't tell you exactly how it was done since it one of those friend of a friend deals that I was able to get a hookup with. But it is possible.

2005 America, green/gray, gutted stock pipes, tall sissy bar w/ luggage rack, Saddleman's dual touring seat and Tourmaster saddlebags (and sissybar bag).
