Default Cutting off catalytic converter

Im thinking about just cutting off my catalytic converter and running straight pipes all the way back. Does anyone have any idea what its gonna sound like? I also have 2 flowmaster exhausts (one installed already, one not) How will it sound with the catalytic converter removed and the flowmasters placed on to straight pipes?

as long as you have the flowmaster mufflers on it i think it will sound good. dont just go straight pipes all the way. it will sound like crap.

or you could just replace your cats w/ some high flow cats then run the pipes back to the mufflers and out the back. and if you want loud, put turndowns right after the mufflers so the exhaust exits under the car and echos. it will sound bad a$$

how much do you think that would cost? parts and labor, i dont trust myself to do any of that work myself. i like the idea with the turn downs but i like the look of straight pipes. all the same, whats the cost on that work?
