I added a Jardine slip-on to the bike some time ago but the guys I ride with mention fuel smell when riding behind me. There are no performance issues. Do I need to remap this puppy - I always thought that if just a slip-on, no re-mapping (or Powercommander) would be needed. Thoughts?

 

a slip on no you dont have to remapp it the exhaust just come's out of the can faster
