99 Ford Ranger Exhaust, dual exhaust?

I've been looking at the Flowmaster Cat-back system for my Ranger, 99.

I looked underneath and couldn't conclude on my own terms weather or not my truck is already a dual exhaust.

It looks like it is, but I'm not sure I'm looking in the right place, so I'd just rather be sure before I drop money on something that won't fit or something I'd need to pay more money to put right.

Do any of you know with out a shadow of doubt that the 99 Ford Ranger 3.0 V6, 2x4 has a dual exhaust?

Please let me know,
Thanks.

No, from the factory there was no dual exhaust. Your confusion may be due to the fact that there are separate pipes from each bank of cylinders, but they collect together at the y pipe, and then go through the catalytic convertor, muffler, and finally the tailpipe. If you decide to go to a true dual, don't forget that the two O2 sensors will have to be placed before and after the catalytic convertor, or you will be upsetting the ECM, and thereby illuminating the dreaded "check engine light"!
