Everyone has a opinion on this topic, do a search. My opinion, i had a F/M 40 and loved it, but when i installed the Magnaflow it was night and day in the performance category. The M/F out performed the F/M big time.

I have the FM 40 with dual outlets on my truck. I ran 3 mph faster than another titan at the track who had a magnaflow, we both had aem intakes other than that. My muffler was on the truck when i bought it so idk from experience the difference it makes or if his truck is just slower for some other reason.

My exact experience here.....What little difference you might get out of "mufflers" is no big deal...
Just a name that costs you more or less...

My Performance improved when i did the switch from the 04 pipes with the F/M to 07 pipes with the M/F. The 07 pipes do flow alot better than the 04-06 pipes. The best bang for the buck is the 07-08 exhaust with your choice of muffler, most guys are giving those pipes away. Just my .02.

ive got an 04cc with dual flowmaster 40s, and i love it.
not sure what it did for performance, but it sounds great.
has a good low purr at low rpms, and it just roars when i go full throttle.

but ive heard nothin but good stuff about jba and magnaflow on here too. so id say just read up on all of em yourself, and make your own choice.
