STOCK VS MODIFIED
When you look at the peak figures on these curves, the addition of Termignoni exhausts does not appear to make a huge difference. However, the big bonus is not only a 2.16lb.ft boost in peak torque, but that its peak output has been shuffled back to 4800rpm, giving the 1100 a much harder punch. From 3000-6000rpm, the power curve is more like a diagonal power line... There are sizeable midrange gains to be had with some dyno time.
