Pics of 99-01 bike with exhaust intended for 03 or newer Vegas
The engine architecture is the same on all Victory engines 1999-2017. The differences are in the swappable exhaust flanges. 1999-2005 92inch 5speed bikes had one style of headed flange, and the 06-17 bikes had a different flange. Again they are swappable (or the holes can be elongated) as needed.
Then the only thing will be to do a little trimming on the RH side panel and fabricate your own bracket to hold the mufflers.
I’ll attach some pics of bikes I’ve done in the past….
Enjoy and feel free to ask questions!
