need advice on which way to go...

[ProStreet83C10]

ok so my plans are to lower my truck 4.5/6 and do 15x10 wheels out back with 315/60R15 tires, give it somewhat of a mini tubbed racey look, my question for you guys if when i lower it im definitely going to ditch the trailer hitch, and probably cut the exhaust back either ahead of rear axle and dump it OR cut it at the downward bend at the axle and dump it there. The reason i say probably cut exhaust is im not 100% which way to go depending on what i end up doing out back for a bumper, which leads me to my initial question regarding this post.

Do I:

1. Buy a sport bumper for the rear
2. Buy a roll pan for the rear (if so i need specs on what to look for)
3. Leave it how it is

Heres some pics of how it sits/looks out back now, and im thinking when i lower it.....its gonna have to change to look right.
