Both are known to make great products, but my vote goes to magnaflow next time if you use the search function you would find hundreads of threads about this topic.
Hope this helps

Magnaflows are a straight through type and perform better every time. They are all stainless steel with a lifetime warranty. The normal flowmasters are not stainless, they may make a stainless version though, I'm not sure. Flowmasters are a chambered/baffled design so they don't flow as well. Sound is all up to the person...I honestly prefer magnaflow, they are much quieter at low rpm's IMO.

note: none of the REALLY fast guys run flows..but seems like alot of the really lightly modded guys run flows and notice it's mostly "it sounds awesome" as opposed to performing better..

This is like comparing apples to oranges but I had a Flowmaster cat-back on my old F-150 w/5.4 v8. It sure sounded nice, but I honestly didn't notice any performance gains. If there were any they were minimal.
I went with a 18" Magnaflow muffler (used stock piping) and I have to say that I will never go back to flowmaster. I noticed a nice bump in performance and it sounds great. Mellow while cruising and nice deep growl when I get on it. I am one that likes to do performance mods for the performance gain, not the sound.
I know comparing the two engines is like apples to oranges, but a simple muffler swap made two completely different outcomes.
