I'd get 'em both replaced. As a general rule, I've always stayed away from the big guys, Midas, Aanco, Etc.. in favor of the Ma & Pa places. My last muffler and pipe replacement was under $150 on the F-250 dual short pipes. Had 'em terminate in front of the rear wheels for boat launching.

yes it will. it will run a lot better. no back flow back into the motor, more performance, better gas mileage. the exhaust will sound a little louder but if thats what you want, go for it!
