Help with exhaust build

I have a v6 Tacoma 2wd I am going to start on my exhaust for my next mod. I am in a toss between 2 set ups.

1. jba shorty headers welded into the stock cats, urd y pipe with urd o2 sensor simulator, jba cat back exhaust.

2. Jba long tube headers,urd o2 simulator, stock y pipe, jba cat back exhaust.

I am looking for low end to mid range hp and torque since it is a truck and top speed isn't the main point of a truck.
Any thoughts and help would be greatly appreciated.

 

If I was to do long tubes there would be a new for the o2 simulator because the front to are the ones that register the most (as I was told). Why would you go doug thorley shorties over Jba shorties?

 

Hijacking....
On the same subject, I looked at my Y-Pipe and it's smashed flat with the cross member. Is there anyone that makes a street legal Y-Pipe except for the factory? Or should I look into saving my coin for a custom. Mine is totally stock.
