Opinions on aFE Exhaust systems?

[scraph]

In consideration of the great deal currently on aFE exhaust systems ... what is everyones opinion on them? I understand the SS is 409, not 304, but I understand and accept those differences. As far as the 4" pipe ... pipe is pipe. The muffler has a straight through design same as all of the others (and the system seems accepting of a muffler delete pipe same as all of the others). I guess the question remains ... are the mandrel bends just as free flowing as in MBRP or Magnaflow systems? ... is the system just as good as the others? If not, why not?

Thanks.

4" exhaust is 4"... Once you get to a mandrel bent system there is not much you can do. I have a MBRP dual kit, but the wife has a Dimond eye... Both look EXACTLY the same, the differance is about $500...
