I am looking into getting a Flowmaster super 44. What would be the difference in a SI/DO vs. running the true dual mufflers?
would it be the same sound except louder?
or would there be a higher or lower tone to the dual mufflers?
any help is greatly appreciated!

 

SI/DO will perform better, true duals will sound a little better. True Duals wont be louder, but it will have a dual sound to it. Unless you have a CAI, and custom tune for true duals, I wouldn't suggest going that route, unless you do, or have plans for those modifications, otherwise your kissing your low end torque away. Bad enough your chosing Flowmaster mufflers but thats your choice, and its gonna sound good.

 

x2 exactly, but true dual super 44's will sound mean as hell!

 

I have a true dual super 44 with magnaflow x-pipe, 4x18 slash cut tips behind the rear tires, and it has a real nice rumble to it. I had a super 40 si/do before and the true dual is def louder! I love it! I will try to get a vid as soon as possible

 

Thanks for that info darren. as of now I think I'm going to go with the SI/DO.
And countryride, I'd love to here that video!

 

What's wrong with Flowmasters?

 

alot of people dont like flowmasters because they will rob you of your low end torque and they will hurt your fuel economy, thats why many people go with magnaflow, or a non chambered muffler, i myself love my true dual flowmasters and dont see myself changing them

but when i get my car, i will not put flowmasters on it borla stingers

 

i havent noticed any loses from having my flowmaster.....

 

i havent either, but im just tellin why alot of people dont like flowmaster mufflers

really i could care less i love the way they sound

 

I've often wondered if the lack of backpressure in Flowmasters would affect bottom-end torque. I guess in a 5000 lb. truck you need as much torque as you can get, but I'm still gonna put them on my '66 Mustang when the time comes.

 

Aluminized Steel construction, and chambered design.


A Flowmaster 2 chamber is better than an OEM muffler, especially with an F150 since our OEM exhaust systems are so restricted. But, its not designed for 100% performance which straight through mufflers are, better economy, and performance with straight through mufflers, and a deeper, richer, clearer note, with very little interior resonance. People have their preferences.

 

Darren, What would be a good magnaflow SI/DO muffler that would be around the same loudness as the super 44?

 

hahaha theres not one, magnaflows arent all that loud they just have a nice sweet sound to them the smallest si/do maggie is a 14" i do believe

 

I'm going against Darren (sorry man!) every MM owner loves Magnaflow, they don't sound good IMHO. I bought my car and there were Mag's on there and I couldn't stand them, they sounded stock to me. I switched out to Flow's and I was so happy. There is no "hey get out of my way" sound to them. They sound good, but not as good as Flows. Yes, a lot of people hate Flows because of their obnoxious drone's, but like you said, everyone is different. And to be honest, with my Super 44, I picked up MPG's and I my truck feels peppier down low compared to stock. I also barely have any resonance inside my cab.
