I have ran so many different exhaust setups it is hard to count now
first I went in and cut the factory exhaust just before the muffler, SOUNDED LIKE HELL
then I welded a 3 in blown glass pack in place of the old muffler, sounded just like a glass packed 460
then I put a 30 in long 4 in tip exiting at a 45 on the rear bumper. sounded a little more like a diesel
cut the glass pack out and welded a straight piece of 3in exhaust pipe in place of it. got really nasty and raspy
cut the factory exhaust just after the crossmember and ranfactory y to 4 inch starting at the middle of the tranny to a 5 in exiting just in front of the passenger rear tire. sounded a little more like a diesel but it was LOUD
then I went to my current setup which is factory y to a 3-4 adaptor and 4 inch from the tranny back, over the axle and exiting through an 8 in tip 18 in long It is still loud but reasonable as long as you arent hot rodding or pulling heavy loads. I can roll my windows up and carry on a conversation in the cab as long as the radio isnt on(it is loud to).
