what would sound better on a 2006 ford f150 flows or dynomax?

 

its your own ear that has to decide that, you will get alot of ppl saying this over this, and this one sucks.
I have a dynomax bullet SISO and its the one of the cheapest aftermarket mufflers you can buy. It sounds great, without being too throaty and loud. I just wish it was a tad deeper. Mines dumped, so its a little louder then if you just swapped it into the factory system. and retained factory exit.

The Dynomax mufflers are typically a milder tone muffler. They have a S curve design that is free flowing and doesn't produce alot of sound. Someone who wants a little more performance and little sound, Dynomax is a good choice. Flowmasters are known to be quite loud. They have chambers and diverters that scavenge the exhaust more thus producing more sound. Usually deeper and throatier than Magnaflows and Dynomax. I've got Flows on my 01 F-150 and my 06 Stang GT, I love them.

 

The dynomax turbo mufflers are milder, but not the dynomax bullets. They're basically a bigger glass pack.

 

theyre not really a glasspack in the least bit, theyre actually the same design as any straight through muffler out there but in a smaller case so they are a lot louder

id put them as equally loud or louder as the flowmaster super 40 and delta flow 40; a tad less than the original 40. i ran a dumped bullet for a year and my good friend had a super40, both of ours were deep, his was a tad deeper but mine was louder.

dynomax is a better muffler for power gains than flowmaster. just make sure to either dump it under a lifted vehicle so it has enough room to resonate and deepen or install large tips. oneof my friends bought my old bullet and put some crappy side exit ghettobanger tip and the exhaust is rather high pitched (for a v8).

 

OK. I got a 4" od 3" id dynomax bullet for my car once. It's perforated inside with glass packing. It's a glass pack, only 1/2" of packing. Very loud though.

 

Just had a set of flows put on my screw and love the sound. I went with the 50's and not 40's but like they said it is up to you on what sound you want.
