exhaust advice needed, front of tires or?

[dukcaln]

I have headers and two chamber flows. Currently the exhaust stops at the mufflers with 3" turn downs.....sounds great. I was considering making a 90 bend and going 3" pipe out just in front of the rear tires..... now here is my question..... 1) will the sound change and if so better or worse and 2) will it look good. If you have exhaust before the rear please post pic..... if you have suggestion on how you think it will look let me know or if you think it will sound better with or without the extra pipe.....
