I just recently dualed my V6 out and I couldn't be more happier with it. What I was looking for was a good crisp GT sound without the loud resignating sound on the freeway, and I over succeeded my expectations.
Here is what I had done:
I left it with the stock headers and cats.
Removed the Y-pipe, all the 2 1/4 piping and the stock muffler.
Installed 2 1/2 piping, X-pipe with the Turbo Muffler, and used the fat stainless still tips.
After I finished it up I took it over to the Ford dealership and I parked it next to a new 06 gt and we started them up. My V6 ended up having a better sound then the GT.
