I know I will be having an aftermarket exhaust put on my truck from week one {luckily, I have a mechanic buddy who specializes in exhaust systems}. He says Magnaflow and Flowmasters are both good, and he didn't have much of an opinion towards one or the other.

My motor is the 4.6L if that makes a difference.

Anybody tried both ? .....or at least, listened to both ?

Curious,

I have had a flowmaster 50 series on my truck and it rusted out, I switched to Magnaflow and I like the Magnaflow better. I have the 5.4 motor

 

yes, I believe the Magnaflows are stainless..... which if it were typically visible, would be a problem for my "blacked out" theme.... but with a black tip, I think it will be fine.

Thank you,
Fish

 

I looked at comments made on this site about flowmaster and magnaflows and decided to go with magnaflows and I have been very pleased with them. Nicer sound in my opinion.

Another vote for straight out the back!

 

 

Flowmaster sounds good, and idles loud. But overtime ( if you suffer witners ) they will rust and will probably need replacing after a year or two.

Magnaflow is much quieter but sounds very clear & healthy, does not drone in cab like Flowmaster can when overdrive engages. Constructed of T-409 stainless steel, it wont rust out & break apart. May get a little surface rust with the Satin finish muffler but who cares its under the truck. Magnaflows straight through flow design also helps your truck exhale a bit better, combined with a CAI you have a little noticeable power gain.

Edit.

Check out some videos of the trucks on YouTube.
