okay so i installed the hi flow maggies like less than a month ago. its seriously extremely LOUD. Poppin and Crackin my pipes all the way. I have true duals straight pipes. so i need to know whether to go with DI/DO Flowmaster 40 Series or the Magnaflow DI/DO muffler??? any feedback would be greatly appreciated. thanks fellas. and yes it is a V8 5.4l.

 

If it's too loud and you want it quieter, go with Magnaflow.

 

x2 Magna Flow all the way!

 

its not that it too "loud" its just to cracky,poppy, and way too raspy. i like the tone of my truck at idle. its deep and toned. but once u give it gas. its a whole different story. so what i want is loud deep toned sound.

 

I like spintech myself...

 

I have a Maggie, I like the deep tone when I mat the pedal, but over all its not very loud.

You may like the Flowmaster with those high flows, if you still want it semi loud

 

yea i just ordered the 40series DI/DO from sports trailerz. dude they hooked me up for real. $89.00 shipped and everything.

 

Unless you wanna lose more low end with a 40 series.. I say Dynomax Bullets, or the good Flowmasters, Super 44s.

Heres my old Silverado with Hi-Flow cats and Super 44s. My F150 is getting the same system but in 2.5"

X2! Bullets would still give you that loud sound with a better tone.

I love the way your old 6.0L sounded!

 

are u serious that im gonna lose low end?!?!? thats just great! well **** i tried getting the super 44s but they aint got the DI/DO.

 

+1 I use Magnaflow on my truck. The sound is not really that loud. Just that simple bassy feel in it. I definitely like it!

You wont notice any loss in torque. If anything you'll gain, Straight pipes kills your low end more than anything...there are dynos to prove it. You'll be fine.

 

Thank ya. It did sound quite good, sure loved to drink what was in the fuel tank though. And with 3" true duals I was surprised it even moved Scavaging between the pipes was still great.


Oh so you want a single muffler, dont wanna pay for two seperate mufflers? Magnaflow DI/DO then. Super 44 isn't available in DI/DO configuration, but it should be, good idea.

 

imo go magnaflow...

but as usual your askig for an answer which is only going to give you biased results...

because eveyrone will only reccomend what they have.

 

Well I would use Magnaflow too. You cant go wrong. We carry a Life Time Warranty against Manufacture Defects. Im not just saying that cuz I work there Ive had my exhaust on my car longer than Ive worked here. Its a great product.
