if you hold the 18" magnaflow mufflers up to your eye you can see through them. they are the most unrestricted besides strait piped. flowmaster you cant see through because of the chambers and plates. magnflow gives you the best flow and horsepower. i have em on my 96 ram and dynod them compared to a 40 series delta flow ((flowmasters best flowing muffler)) and saw a 6hp differance and 11lb/ft differance. go with magnaflow. flowmaster is louder at idal but the magnaflow sounds awesome when under acceleration.

Flow comparison for the same physical sized mufflers.
Flowmaster 40 series = 200cfm
Magnaflow 14" = 410cfm
Twice the flow with a nice deep tone. Not all crackled and poppy like video 5 post above.
MMSTAR, welcome back, I haven't seen you around in awhile. No more sludge problems?

That is possible.
I had both on my 01 F150 that I had. The sound wasn't alot different due to it having 4 cat converters, but the Magnaflow did make a little more power. The Flowmaster was rotting off after 4.5 years. Replaced it with a Magnaflow. Stainless it the only way for me now. Do it once and do it right!!
