Just bought a 2013 Edge Sport. Looking to do a custom exhaust. Any advice on how I should do this? Thinking of going with a X pipe and Flowmaster 40 series mufflers. Do I remove the middle resonator and just put a Flowmaster muffler there and eliminate the rear 2? Or can I delete the resonator altogether and put 2 Flowmaster mufflers in the rear? Any tips would be helpful. Thanks
