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?

My suspicions exaclty I think the system does little more than make the stock outlet look better.

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.

Does it interfere with regen at all?
