Side exit exhaust question

My system now is exiting behind the right rear tire. Will I get a tremendous noise increase in the cab if I have it exit in front of the rear tire? I'm thinking it'll be a little cheaper, easier, and lighter by not having all the extra piping.
Current system is: Ahr 1 7/8 headers and cats with a Gibson dual sport cat back.
Going to: same headers and cats, x pipe with daul dynomax ultraflows all 3 inch.

My brother has a 4.8 with a flowmaster catback that exits in front of the rear tire and surprisingly there was very little drone. Obviously in your case your setup will be louder, but from my experience the drone wasn't too bad with the exhaust ran that way.
