hi, I have a 2007 Edge SEL and i would like to remove the middle muffler (resonator) and put a stright pipe and add two flowmaster 50 delta flow in place of the back 2 mufflers. is that fine? did any one did 2 mufflers at the back? most modifications on here are replacing the resonator with flowmaster or magnaflow and removing the 2 mufflers at the back. is there a reason for doing that? Thanks

Hi, is it still available?
