I have a 2006 VTX 1300S. I really like the look of the new tapered exhaust pipes on the 2009 and and newer models. Will the new mufflers work with the existing pipes on the 2006 model? Could they be changed out easily? Where would be the best place to purchase the mufflers? I think I saw the HDL price to be over $1300 just for the two mufflers!! That may be a deal breaker. Thanks.
