Y Pipe into H Pipe?

Hey guys, I know there is a massive thread already on dual exhaust conversion for the V6, but there really isn't any information specifically tailored to what I need. Currently I have a stock exhaust system, aside from the axle back. Shortly in a few weeks my GT style rear bumper will be coming in and this means dual exhaust. My question lies in whether or not I can buy a GT catted H pipe, with a little fabrication, and it will fit on my V6. If this is possible, aside from the H pipe what else will I need, a Cat Back exhaust system? Maybe straight pipe it all the way back? I'm also concerned whether or not removing the cats and resonators will make my car sound like ****. Loudness I don't mind, I just don't want it to sound like trash. Thanks in advanced everyone.

How does it sound? If you were to change anything about it, start over, what would you have done?
The Flowmaster mufflers made a droning noise inside the car at highway speed so I got a set of stock GT mufflers and put on it. It didn't sound quite as good outside, but sounded much better inside. I like the sound better than a X pipe.
So just to be clear, you picked up a GT H mid pipe, did some fabrication, and used gt mufflers?
No, I got the pipes off of a GT and used the old V6 pipe to make the H pipe. I cut the bends out of the old pipe that I needed to make the Y pipe into a H pipe and welded it together. Then attached the GT pipes and used the driver's side hangers from the GT. If you look at the pictures you will see where I welded everything together. I wish I had taken more pictures, but I didn't think of it at the time. These pipes are made of 409 stainless steel, so it's best to TIG weld them with stainless wire.
I have an 09 4.0 v6 with mid x pipe true daul pypes system i like it the sound has no drone no popcorn effect and as you hit higher rpms the sound gets louder if you want to improve the exhaust note then you want headers to go along with your exhaust system.
