Had shoulder surgery a month ago and as my own prescribed rehab I installed my stage 1 upgrade.

Finally able to ride for the first time in 5 weeks yesterday and bike sounds great. Not overly loud but just a nice deep Harley rumble. Butt dyno says no noticeable power loss from the switch to true duals either In fact seems to be a more constant and steady power band through the range I rode in yesterday.

 

Well you have chosen some excellent equipment, and the performance will reflect that. I don't doubt the experts that say a true dual setup will produce less power than other configurations, but I wonder if it's noticeable by 'seat of the pants' dyno tests.
