As for performace per pound, I reckon a decat and cat back exhaust system would give you similar gains for similar cash, the only way to get much better gains through an exhaust system is to fit a new manifold, and then the cost of the exhaust is way higher than the ITG kit.
decat and full 2,5 inch exhaust from the manifold back and im sure ud see alot better performance than u do change'n the filter
