Just noticed previous owner removed baffles, affecting performance?
I didn't think we printed out any BCT charts, and I've gone thru our stack of dyno charts and could not find any. They were not slated for comparison that day...we just did it for grins and giggles, on the spur of the minute, since there was a set sitting in the dyno room.
But you can look at the charts on the TTI's, to see what kind of power gains you can get out of them, at this LINK
Here's a typical chart of an 883 with free flowing exhaust with & without the TTI's installed.

There is no other baffle than can make such a radical improvement, nor is there any other mod that gives as much gain in power, per dollar spent, as the TTI's do.
