Any preference, strengths, weaknesses? Opinions, advise. etc...

I prefer magnaflow for quality fit and finish, the AFE systems had a few fitment issues when they came out, but that is corected now. What bed and cab configuration do you have. I have a sweet deal on Magnaflow kits for CCSB trucks.

In my opinion, RBP. Its spendy, but well worth it, But between those two, I haven't heard much about AFE, so I would go with that. I like the stuff thats not to common.

Pull off the RBP logo and you will probably see Magnaflow stamped into the metal...;)

No Way

I know it's well known, but why pay more money for a RBP when you can get a the same Magnaflow for less...?

i was told AFE is not as noisy as magnaflow that why i was leaning towards AFE ,is their any truth to that chad what your opinion thanks

Magnaflow 4" kits are a little aggressive sounding due to the short muffler. The AFE kits do come with a larger muffler so they are a little more quiet. Since you have an LBZ, I wouldnt worry about the noise either way, they bot will sound quiet on your truck.

I have never had an AFE exhaust on my truck or spent any time in one with that exhaust, but from my experience, the inside drone of a straight through (AFE, MBRP or Silverline) type muffler is more than the Magnaflow's necked down version. If you really want a quiet exhaust, go with the Magnaflow Dual system, sounds stock in the cab.
