2007 Softail dyno #'s Rush 2.0 slip-ons *UPDATE*
Here is the before and after dyno sheet. The red lines are the stock baseline readings. The blue lines are with the addition of Rush 2.0 slip on mufflers. No other changes made. Note that the correction factor is STD.
The following sheet is the a/f ratio for the roll-on (closed loop) tests.
The a/f ratio was virtually identical before and after the Rush muffler install.

Thanks for the post. I have an '07 Fatty with the Rush slip on's and I'm curious as to the difference myself. They were on it when I got it so I wouldn't know what sort of "seat of the pants" difference they made.

Mine went from 63.99 hp to 75.41 and 78.16 to 87.36 tq. I did rush slip ons and pc lll and big sucker. Stock was done at 91 degrees and the dyno was done at 68.
Rush told me anything over 1.75 and you would loose TQ
