I alluded to this in the sponsors section, but thought this thread would be more appropriate here.
I'm planning on modding my exhaust in the very near future...but can't decide which is the best route to go. Single/Dual -- and which manufacturere (only a few choices right now).
If anyone else has already done this...would love to see the results. There's another company (Borla) that has a cat dual exhaust out for the Armada. Would love to know which has the best hp/torque gains. And...it's crucial that I not lose any of the low end torque I have now.

I will tell you now I love the sound of my dual in/out Flowmaster setup. But I did low end Tq. I will be testing the Gibson Single in out as soon as it gets here. They are supposed to give some nice gains and still sound good. I will let you know.

Cool -- looking forward to hearing about it -- see if you can't stick that thing on a dyno while you're at it. Sound is of no real importance to me...performance...is the only thing that matters.

Asking for a little technical help...or personal experience...on modern dual exhausts.

On my 65 Mustang, the dual exhaust is completely dual - headers running into separate pipes to separate mufflers all the way back. In the words of a redneck buddy, "It's just Dual!"

For the Armada, the exhaust manifolds merge into a single pipe to a single CAT to a single muffler. If you convert to a "dual exhaust" from the cat back, what kind of performance gain are you really getting? Would you get close just changing out the single muffler?

And lastly, what kind of work is involved hanging the cat-back dual exhaust setup?

I could be wrong but I thought that the exhaust on the Titan and the Armada were exactly the same. If so then your cats are before the joining Y pipe and just a little after the headers. The cat back bolts to the cats then to a Y pipe if you go with single in to the muffler then dual out which is not a true dual exhaust. It is probably a petter performer though. I have the dual in dual out and I lost torque. If you dont mind this then my set up would be great for you. Also what level of noise are you willing to put up with. Mine is noticable if you know what I mean. It turns heads. Its the 50 series Flowmaster dual in/out. I will be getting the Gibson single in out sometime in the next week to do a comparison.
Keep coming back and I will have a review over on www.clubtitan.org

i'm interested in a dual exhaust myself! but i do not want to lose any torque! in addition, i DO NOT want it any louder than it already is. if anything, i'd prefer it to be deeper sounding......but i do not want my 'mada sounding like a rice rocket!

any suggestion guys?

m4ck.....did you get any dyno numbers from your setup yet?? Would be interested in seeing what the performance improvement was -- and if you lost any torque at one range of rpms...to make gains in another. I'm still torn as to what I should do in this regard to my Armada.

Almost all free flowing exhausts are gonna make you lose torque on these trucks. It is a hard call, torque is what really makes these motors rock.

The Gibson is supposed to deliver both HP gains and TQ gains if thats true thats the Pipe I wanna run. Let us know.

Borla Adds Torque

I have the Borla exhaust system on my Armada and it sounds mean, yet refined. It has a really deep throaty low bass sound, without that hollow pipe sound of the others I considered. My wife and 5 yr old daughter drive this every day and I didn't want it to sound like a farm truck that needs a new exhaust system. Plus the standard welded on finish tips (with built in sound baffles) look like they are cannons pointed at the guy behind you. Borla has great quality reputation and performance engineering, read copy and pasted ad below, found on www.truckperformance.com or go to www.borla.com , I got mine for $740 with shipping and installed for $50 at the local tire/exhaust store. I tow a '20 cuddy boat and feel the extra power and very little noise differance in the vehichle at idle and deep rumble as it rev's up.

"Borla Performance Industries T-304 stainless steel rear section systems are made for race, street, and off-road. Borla systems are built for those who want the absolute best quality exhaust money can buy. Engineered for maximum power with a distinctive sound that signatures a Borla system.

The Aramada is not set up this way. The "Y" pipe bolts up to Cats on each side, then to the muffler.
I have the Gibson 3" single on my Armada. I did not loose any low end torque, in fact it feels like it made a slight increase. A "true" dual system will loose low end torque on the Armada. IMO the Gibson single is the best choice for most drivers. I think the Gibson "Y" pipe is the best made you can get. Nice bends and all one peice, no joints like some others have. The pipes also flow very smoothly into the collector. The muffler is a straight through 3" core, with no packing to wear out.

Did you mention a resonator? Is this the muffler or an additional piece?
After the Y merges, the stock setup just goes through the muffler and out the back.

There is a small resonator on the Gibson.It is 3" in diameter and installs between the Y pipe and the muffler.
