Catback and back pressure

I have 1990 honda civic DX and already have 1.5 - 2 inch pipping (not sure bought it like that) wonder since I have no emmision laws where I live if I cut out my cat will I gain hoarse power or loose it to back pressure, I also have an aftermarket dragonfire Muffler.

i don't believe you'd have a backpressure problem, i would imagine you;d get more HP without it. Personally, i'd install a highflow cat or a straight through pipe like you can find on ebay.
