I can tell you that the TOR's are not breathing as easy as the Thunderbikes...even the straight thru ones (I had those) and at 135's (no freak) I was rich...now with the SS pipes the bike is much happier so the TOR's can throw your #'s off you can dial those pipes in nicely but they (Triumph) has SOOO many different versions you may find Pat's calcs a bit off from reality (only because of the different versions not because of his software)
