flows sound good but magnaflows sound good too and perform better. its a matter of personal preference. itd be best to hear a few differnt exhausts in person before deciding.

 

Another vote for Borla (Borla builds the Roush Offroad ).

 

magnaflow over flowmaster hands down...borla is 304 and rich note like darren said, cant be beat

 

18" Magnaflow. Mo shiney den da Flo an dey sound mo gooda! Had both a dem.

 

I've had both on my truck...and I have to say, I liked the sound of the Flowmaster better (especially in lower RPMs), but it did drone in the cab quite a bit, so I chose to have a pretty quiet Magnaflow installed. The only place you'll notice a difference in power between the two is on the dyno.
Advantages/Disadvantages of Flowmaster (just some of my opinions) :
A: sound
D: not made of stainless (though they have started to do so)
D: too loud for my tastes
D: wasn't fond of the crackle/pop of the higher-RPM sound.
Advantages/Disadvantages of Magnaflow:
A: still sounds good. IMO, better than the flowmaster at higher RPMs.
D: ^^but overall not as good as the flowmaster I had in place before.
A: stainless steel. Still looks shiny and newish
A: no cab drone
D: possibly a little too quiet for my tastes...but high-flow cats might fix that problem


...Hope this helps. Note that my Flowmaster was an Original 40 series si/do setup, whereas my Magnaflow is a 3" si/so catback system.

 

who cares get what u want

 

sorry but id have to say gibson gives the best roar without being too loud a buddy of mine has gibson duals on a '04 regular cab it sounds pretty good...
but i have true dual straights with the 5.4 pullin 35s... yea i gotta say mine is pretty loud

 

I put the SIDO Magnaflow system on my 2010 lariat and it sounds great, but might not be as deep as others. I've been thinking about switching to a true dual setup with Flo-Pro x muffler like on the Kinney's video. I talked with Kirk down there and he said that it's the best setup he's ever done on a f150. I may end up selling my Magnaflow bolt on to someone here if interested.

 

^ You will be disappointed...

 

after reading this thread im back to square one i want something that will sound good but performance is always better then sound. back to the drawing board.

 

if you want both magnaflow is a great choice. sounds great and preforms well. i've had flowmaster super 44, magnaflows and banks. hands down magnaflow is the best overall. flowmasters have way to much crackling. I love my banks though real aggressive when getting on it and no drone.

 

Magnaflow is amazing sound with performance, just hit the "Order Now" button.

 

^ Agreed

 

The flowmaster super44 I had on my truck sounded incredible above 3k rpms...which my truck spends .05% of the time in that range. At lower RPM and idle, the Borla made Roush Offroad muffler sounds far superior. Very unique, deep tone without the resonance in the cab. I do wish it was louder though, having 4 cats sucks.

 

Just put any kind of aftermarket muffler on there.... they will all sound good. All local muffler shops have deals on exhaust setups, just use what there offering. No Cherrybombs.
