4.7 dual exhaust with flowmaster review

4.7 dual exhaust with flowmaster review
2000 Dakota quadcab 4x4, 4.7 V8, auto.
I cut the factory muffler off, welded in a single 1 inlet and 2 outlet flowmaster 40 series muffler. So thats 2 manifold pipes into one(factory), then into one flowmaster muffler, 2 outlet pipes from muffler strait out the back near middle by hitch. I am very pleased with sound. I get asked by strangers everyday what kind of setup I have. They can't believe it's a 4.7 liter. Very deep, throated sound from idle to highway without the raspy, metal bucket sound when you get own it. INTERIOR NOISE is probably a 3 on a 1-10 scale with 10 being the loudest, muffler directly under back passenger seat. EXTERIOR NOISE is 7-8.5 maybe. Not that stupid what a teenage likes loud but you're not gonna sneak up on anyone either. Cannot determine any mileage gain, perhaps a slight power gain or maybe I just feel more powerful with that grunt sound. Most 4.7L I've seen with TRUE dual exhaust sounds way too raspy, weak and high pitched as rpms climb due to not enough back pressure and loss of torque due to this. But all this is just my opinion and Most muffler shop techs I talked to while researching mine.

Yours isnt a TRUE dual exhaust. deffinition of true duals is one exhaust coming off the right bank straight back. and one pipe coming off the left bank and straight back. 2 completely different pipes and technically 2 completely different systems.

True Duals
Apparently there's a bunch of illiterate retards in here. It was a COMPARISON to a truck WITH TRUE DUALS, never was it stated as having true duals. Thus the reason for the DETAILED description of the set up. GOOSHHH! I thought I stated it simple enough but apparent not. I think any idiot that read "single muffler" would know it's not "true duals" but a couple of you feel the need to state the obvious to those of us that already get it.

I have Magnaflows on my Magnum and they sound sweet....took the middle resonator off and Holy Crap it was awesome..... true dual on both vehicles would be the best.
Thanks
