Magnaflow claims there is is a 29hp gain and 49ft torque gain with there 5" DPF back system. Has anyone put this on there their truck yet? Does it sound any better? can you feel a power difference?

I installed one using the supplied muffler(they supply a muffler delete pipe also). Sounds slightly different, runs no different, looks cool though. 2008 F450 auto w/4.88. AFE intake seemed to make more of a difference is sound and power.
