06 GT Mufflers
will the mufflers alone increase horsepower or will i need to get new tubes as well, also will they provide any better of a sound? I have the stock V6 exhaust right now and i am willing to spend the money on a true dual exhaust, just need to find the cheapest/best way to do it

I bought a 2006 v6 mustang with a single exhaust. I upgraded to true dual exhaust about a year ago and I don't regret it! My mustangs sounds pretty nice right now, still want to add long tube headers. But anyway here is how I got my setup going
Stock GT mufflers $80
Exhaust parts -$170 got everything I need on rockauto.com
Installation at my local muffler shop (south Texas) $100
For $350 it's not that bad of a upgrade but with $350 I would much rather get a cold air intake and a coil pack as my first upgrades. Then the dual exhaust

You are right. It doesn't do much, but the sound and the response is much better with the dual exhaust. That was the very first mod, other than tires/wheels that I did to my car. I originally just did a bumper cut for the left side exhaust, but later put on the Ford CS/GT rear fascia (7R3Z-6320049-BA).
There is definietly a seat of the pants feel with the dual exhaust over the stock, restricted muffler. The GT dual mufflers, release much of the back pressure, so there is some effect of power that can be noticably felt.
The CAI and tune make the most additional HP for this motor. Adding an Underdrive balancer is suppose to help some, but I haven't gone an purchased one of those yet. Maybe this winter for a spring install. I just haven't been sold on the cost vs what is accomplished yet, but I'm sure that the difference can be felt when accellerating.
The biggest power to ground add is the gearing at the differential. I went from 3:31, 7.5 rear differential, to 3:73 first. WOW. Night and day difference. I have since stayed with the 3:73's but have gone to a 2011 GT 8.8 rear differential to replace my 7.5 rearend. I had no problems with the 7.5, but when I found a 2011 for $400, I had to snap it up. I sold my take out for that much to a guy who is racing his Mustang with that rearend. He just pulled a 12.8 with a V6 in an 05 Mustang. Not bad for a 125k mile engine and car. lol
