would getting rid of that chokemaster muffler and running a dump off of the y-pipe help me out power wise? or would i lose too much backpressure and do more harm than good?

I don't see how improving exhaust flow could ever be harmful to horsepower. It might shift the torque band upward a bit, but there won't be any peak HP loss from deletion of a muffler. Many race cars have open headers with turndowns or cutouts. If you have LT headers with collectors, then you have plenty of "backpressure"....anything beyond that is just a streetability compromise to reduce sound levels and move exhaust fumes further away from the cabin.
