parker, i had a 120 with no mods other than a decat and it gained 6bhp and 6ft lb of torque :) as berto said, pickup was better, felt more responsive and the torque curve was a lot smoother and less choppy.

I have 4-2-1 Janspeed manifold and sport catalyst on my 160. Just a very slight improvement, nothing more
thats because your bottle necking the gain with a standard system past there

you have to have the manfold if u have a sports or de cat as there not compatiable and part of the gain isloosing the restrictive manifold of the zr
