well a 4-1 sends most of the power higher up in the rev range anyway and if its an x14xe or x16xe then they are crap before 4,000 rpm because of the ecotec. could you have damaged the lamba sensor when u put the manifold on?
also when u de-cat a car u loose some of the low down power because u loose back pressure. well i did on my old saxo so if it has a de-cat aswell then maybe ur just loosing backpressure..

pretty much every 4-1 is like that and they dont normally cause problems, have you got engine management light on?
